Examination of the Cardiovascular System

Examination of the Cardiovascular System The child should be undressed appropriately to the waist. In the older child, the examination easily performed with the patient sitting over the edge of the bed or even on a chair. Preferably, examine the younger child on the parents lap. Removing a toddler from his parents is less likely to yield good clinical signs and more likely to yield a screaming child. For examination of femoral pulses, the child should be in the supine position. Warm your hands by rubbing them against each other. STEPS OF THE TASK You should use the middle three fingers of your dominant hand to palpate the pulses against the underlying bone. The finger tips are used for palpation as they have maximum sensitivity. While palpating, the artery is stabilized by the proximal and distal fingers and the thrust of the pulse is felt by the middle finger. Partial occlusion of the artery by the distal finger improves the thrust of the pulse wave on the middle finger. Palpate all the pulses listed below first on the right and then on the left side. Always compare the respective pulses on both sides except the carotids. In case of carotids, palpitating both sides can induce cerebral ischemia and can cause the patient to faint. Carotid (dont palpate both sides simultaneously) Palpated at the level of thyroid cartilage along the medial border of the sternomastoid muscle either with finger tips or thumb (left thumb for the right side and vice versa) Brachial Palpated with the elbow flexed along the medial aspect of the lower end of the arm Radial felt at the lower end of the radius on the anterior aspect of the wrist, medial to the styloid process with the patients forearm slightly pronated and wrist semiflexed Femoral (DO NOT FORGET FEMORALS) felt in the middle of the groin with the leg slightly flexed and abducted and foot externally rotated. Dorsalis pedis can be felt on the dorsum of the foot lateral to the extensor hallucis tendon in the middle third of the foot Posterior tibial felt posterior to the medial malleolus and anterior to the Achilles tendon. For assessing the pulse rate, use brachial pulse in an infant or toddler and radial pulse in older children While counting the pulse rate, count for 15 seconds and multiply by 4. But tell the examiner that ideally, you would like to count for one minute. However, if the pulse is irregular, then count for one full minute and also count the heart rate by auscultation. Rhythm while looking for the rhythm, one looks for the gap between the pulse waves and comment on their regularity. Volume This is a highly subjective sign. It describes the thrust (expansion) of the pulse wave and reflects the pulse pressure. If high volume, always check for collapsing nature. (Hold the right forearm of the patient by your hand in such a way as the radial artery is under the head of the metacarpals of our hand. Lift the patients entire upper limb vertically by 90à ¯Ã¢â‚¬Å¡Ã‚ °and feel for the sudden and exaggerated rise and fall of the pulsations of radial artery.) Character This describes the form of the wave and various types are decided by the rise, peak and waning of the wave. It is best appreciated in carotids. Radio femoral delay (femoral pulse appears following a time delay after radial suggests coarctation of aorta) POST- TASK Make sure you dont leave the child exposed. Thank the child/ parent for co operation if no further examination is planned VIGNETTE Characteristics of pulse should be described as follows Rate Rhythm Volume Character Symmetry Radio-femoral delay Rate Comment on rate as normal, tachycardia or bradycardia based on age specific heart. In general, for children over 3 years of age pulse rate >100 beats per minute is tachycardia and pulse rate Tachycardia has poor specificity and always make sure child is not anxious/ febrile before attributing significance Bradycardia in a child is usually point to underlying pathology once exercise (athletes), drug intake (Digoxin, beta blockers) is ruled out. Rhythm Reported as regular, Regularly irregular and Irregularly irregular Regular there is a normal variation of heart rate on breathing sinus arrhythmia. It is present in most children. Regularly Irregular: abnormal beats occur at regular intervals pulsus bigeminus, coupled extrasystoles (digoxin toxicity), Wenckebach Phenomenon Irregularly Irregular no specific gaps between the waves Extrasystoles are common in normal children and disappear with exercise. Atrial fibrillation is another common condition which causes an irregularly irregular pulse. Comment on the pulse deficit i.e. the difference between heart rate and pulse rate Volume High volume anemia, carbon dioxide retention or thyrotoxicosis Low volume pulse is seen in low cardiac output states. Character Slow rising and plateau (pulsus parvus et tardus) severe aortic stenosis Collapsing pulse e.g. aortic incompetence Pulsus Paradoxus- pulse is weaker or disappears on inspiration e.g. Constrictive pericarditis, tamponade, status asthmaticus Jerky pulse normal volume, rapidly rising and ill sustained.-suggestive of hypertrophic obstructive cardiomyopathy Pulsus bisferiens two peaks felt during systole, seen in the presence of moderate artic stenosis and severe aortic regurgitation Pulsus alternans Pulse wave with alternate small and large waves seen in severe left ventricular failure and arrhythmias Symmetry Unequal or absent pulses may be suggestive of previous surgery e.g. Blalock-Taussig shunt, repaired coarctation, cervical rib or absent radial pulse OSCE CHECKLIST PRIOR TO THE TASK Hand washing or using alcohol rub Asks the name and age of the child, if already not told by the examiner Explains the purpose of his/ her visit and what he/ she is going to do Positions the patient appropriately TASK Uses the middle three fingers of the dominant hand to palpate the pulses Palpates all the pulses first on one side and then on the other side Compares pulses bilaterally Does not palpate the carotids simultaneously Counts the pulse rate at least for 15 seconds If pulse is irregular, then counts for one full minute and also counts heart rate Looks for Radio femoral delay While describing the pulse, comments on rate, rhythm, character, volume, symmetry and radio-femoral delay POST- TASK Makes sure that the child is not left exposed Thanks the child / parent for co operation Task: MANUAL Measurement of blood pressure PRIOR TO THE TASK Mercury sphygmomanometer should be used as aneroid sphygmomanometer loses accuracy on repeated usage. Choose the appropriate size cuff the cuff bladder should cover at least 2/3 of the length of the arm and 3/4 of the circumference . Cuff size should always be documented. Make sure that the child is calm and not crying or agitated Child can be either seated or in the supine position Any clothing over the arm should be removed THE TASK The convention is to measure BP in the right arm in a calm but awake subject. If conditions differ from this they should be documented with the reading. The elbow should be supported and flexed and should be at the level of the heart. The cuff is wrapped around the upper arm with the bladder centered over the middle of the arm. Approximate estimation of the systolic blood pressure is done initially by inflating the cuff fully and then deflating slowly and smoothly while palpating the radial pulse. Systolic blood pressure is noted at the point when the radial pulse returns. Following this, the blood pressure is recorded by auscultatory method which is the more accurate measure. The diaphragm of the stethoscope is placed over the brachial artery along the medial aspect of the lower end of the arm below the edge of the cuff. The cuff should be inflated to 30 mm above the palpatory systolic blood pressure and then deflated slowly and smoothly at the rate of 2-3 mmHg per second. Systolic blood pressure is recorded at the point when clear, repetitive tapping sounds are just heard. Diastolic blood pressure is recorded when the sounds disappear. In some children, instead of disappearing, the sounds muffle first before disappearing. In this case, the value at which the sounds muffle should be recorded as the diastolic pressure if the difference between the point of muffling and disappearance of the sounds is greater than 10 mmHg. POST- TASK Make sure you do not leave the child exposed. Thank the child/ parent for co operation if no further examination is planned While interpreting the readings, the state of the child should be taken into account. Values should be compared to normal values with reference to the age/height and sex of child. VIGNETTE In infants, instead of radial, brachial pulse should be palpated. Sometimes, auscultation can be difficult in infants in which case systolic pressure by palpation should be documented. If measuring a lower limb pressure, the same cuff can be applied to the lower leg and a foot pulse palpated. It is advisable to measure the blood pressure in both upper and lower limbs. When coarctation is suspected, it is imperative that blood pressure is recorded in both arms and one leg. The same should be done is cases of hypertension and in those who have had shunt surgeries as in Blalock Shunt. While recording blood pressure in the lower limb, a larger appropriate size cuff should be used and auscultation is done over the popliteal artery. The sounds which are heard while auscultating are called as Korotkoffs sounds and has five phases. Phase 1 is the first heard clear, tapping sound, phase 2 is intermittent murmur like sound, phase 3 is the loud tapping sound, phase 4 is the muffling of sounds and phase 5 is disappearance of the sounds. Occasionally, the sound might disappear after the Korotkoff sound phase 1 before reappearing later. This auscultatory gap can lead to either underestimation of the systolic blood pressure (if prior estimation of blood pressure by palpation is not done) or overestimation of diastolic blood pressure is the auscultation is not continued till the end. In atrial fibrillation, phase 4 of Korotkoff sound should be used for recoding diastolic blood pressure. Pulsus paradoxus is best appreciated while recording blood pressure by auscultation and is identified by recording the value at which the tapping sounds are heard only during expiration and the value at which the sounds are heard both during inspiration and expiration. When the difference between the two values is greater than 10 mmHg, pulsus paradoxus is said to be present. Pulse pressure is the difference between systolic blood pressure and diastolic blood pressure. A weak pulse is associated with narrow pulse pressure and is seen in cardiac failure, shock, aortic stenosis and constrictive pericarditis. Pulse pressure is wide in aortic regurgitation, hyperthyroidism, anemia and febrile states. OSCE CHECKLIST PRIOR TO THE TASK Washes hands or uses alcohol rub Explains the purpose of his/ her visit and what he/ she is going to do Positions the patient appropriately Chooses mercury sphygmomanometer Chooses the appropriate size cuff Removes any clothing over the arm TASK Supports the elbow and keeps it at the level of the heart. Wraps the cuff around upper arm with the bladder centered over the middle of arm Estimates systolic blood pressure by palpatory method Uses brachial pulse in infants for palpatory method Estimates systolic blood pressure by auscultatory method Uses diaphragm of the stethoscope for auscultation POST- TASK Makes sure that the child is not left exposed Thanks the child / parent for co operation Records blood pressure as estimated by palpatory and auscultatory method including the site and the position of the child Interprets the blood pressure Task: Evaluation of jugular venous pulse PRIOR TO THE TASK The room should be adequately lit for the assessment of jugular venous pulse The patient should be in semi-reclining position with the trunk at 45à ¯Ã¢â‚¬Å¡Ã‚ ° to the bed. The head and the back should be well supported with a pillow under the head. The head should be positioned in the midline THE TASK Stand on the right side of the patient and assess the jugular venous pulse. The torch should be shined from the left in an oblique direction and the jugular pulsation is observed Jugular venous pulse is located just lateral to the clavicular head of the sternomastoid muscle. Pulsations of the jugular veins should be differentiated from the carotid pulsations as discussed below. The jugular venous pressure is assessed by measuring the vertical distance between the top of the jugular venous pulsations and the sternal angle (angle of Louis). In cases where the top of the jugular pulsations is not visible at 45à ¯Ã¢â‚¬Å¡Ã‚ °, increasing the reclining angle up to 90à ¯Ã¢â‚¬Å¡Ã‚ ° can make the top of the pulsations obvious. The assessment is done when the child is breathing quietly Look for hepato-jugular reflex. This performed by exerting firm and sustained pressure on the right upper quadrant of the abdomen and looking for an elevation in the jugular venous pressure by 2-3 cm. POST- TASK Make sure you do not leave the child exposed. Thank the child/ parent for co operation if no further examination is planned VIGNETTE Assessment of jugular venous pressure is rarely important in the younger child. It is also difficult to obtain an accurate reading because of the short neck in children It can be generally measured easily if the child is greater than 10 years Jugular Venous Pulsation Carotid Pulsation Pulse lateral to sternomastoid Pulse medial to sternomastoid Better seen Better felt Multiple waves seen Single wave Abdominal pressure makes the pulsations prominent Abdominal pressure has no effect Valsalva maneuver makes the pulsations prominent Valsalva maneuver has no effect Can be obliterated with pressure Cannot be obliterated with pressure The right jugular vein is in a straight line with the right atrium and is more likely to show the pressure effects than the left jugular vein which has more tortuous course and is more likely to kinked. This can lead to false elevation of the jugular pressure. In patients with highly elevated JVP, the pulsation may be seen only below the angle of jaw. In such cases, increasing the reclining angle to 60à ¯Ã¢â‚¬Å¡Ã‚ ° or more makes the pulsations more obvious. Turning the head slightly towards the contralateral side can make the pulsations prominent, if the pulsations are not obvious. JVP consists of a, c and v waves and x and y descent. a wave is due to right atrial contraction, c wave is due to bulging of the tricuspid valve and v wave is due to atrial filing. x descent is due to atrial relaxation and y descent results from ventricular filling and tricuspid valve opening. The sternal angle (angle of Louis) is taken as the reference point as it roughly corresponds to the middle of the right atrium. JVP is elevated in congestive cardiac failure, fluid overload, constrictive pericarditis, pericardial tamponade, tricuspid stenosis and tricuspid regurgitation. Non-pulsatile elevation of JVP is seen in superior vena cava obstruction. a wave are absent in atrial fibrillation. Large a waves: are caused either by hypertrophied right atrium in response to decreased right ventricular compliance as in pulmonary hypertension and pulmonary stenosis or contraction of atrium against resistance as in tricuspid stenosis. Cannon a waves are giant a waves seen in early systole and is caused by contraction of the atrium against a closed tricuspid valve. It is usually seen in complete heart block and ectopics. Large v waves are seen in tricuspid insufficiency. Sharp x and Sharp y descents are seen in constrictive pericarditis and restrictive cardiomyopathy. OSCE CHECKLIST PRIOR TO THE TASK Washes hands or uses alcohol rub Explains what he/ she is going to do Makes sure that the room is adequately lit Positions the patient in semi-reclining position with the trunk at 45à ¯Ã¢â‚¬Å¡Ã‚ ° to the bed Supports the head with pillow to ensure relaxation of the neck Positions the head in midline TASK Stands on the right side of the patient and assesses the right jugular venous pulse. Locates the jugular pulse correctly If the jugular pulse is not obvious, then makes it obvious by turning the head slightly to the left and shines the torch from left obliquely if necessary Measures the jugular venous pressure correctly Looks for hepato-jugular reflex. POST- TASK Makes sure that the child is not left exposed Thanks the child / parent for co operation Lists the differences between carotid pulse and jugular pulse Task: general inspection of the body with reference to cardiovascular system PRIOR TO THE TASK Introduce yourself to the child and carer and ask for permission to examine For inspection, the room should be well lit. Ensure that the lights are turned on and the windows are open The child should be undressed appropriately to the waist. In older child, the examination is easiest to perform while they sit over the edge of the bed or even on a chair Examine the younger child on the parents lap. STEPS OF THE TASK LOOK GENERAL General well being Well/ Ill looking child Interest in the surroundings Sick child will not be interested Size of the child thin small, thin tall, well nourished and tall, well nourished and short. Degree of breathlessness classify as none, mild or severe Environment (Equipment) oxygen mask, nasal cannula, intravenous catheter, pulse oximetry, feeding tube/ gastrostomy, LOOK SPECIFIC Head look at the size (microcephaly or macrocephaly) and shape (dolichocephaly) Face Normal or dysmorphic features, malar flush Conjunctiva pallor, jaundice (refer chapter on general examination) Mouth Using the pen torch, take a quick look in the mouth and look for the presence of age appropriate teeth, abnormal teeth and caries. Ask the child to stick their tongue outwards and upwards towards the nose and examine the tongue for central cyanosis. Hands and fingers pallor; clubbing; polydactyly and syndactyly; Oslers nodes; Janeway lesions; splinter haemorrhages. Examine both the hands quickly. Difference in colour between limbs POST- TASK Make sure that the child is not left exposed Thank the child / parent for cooperation VIGNETTE Always think whether the findings combine to form a recognizable clinical syndrome. It is preferable to inspect the child in sunlight than in artificial light. Children with chronic cardiac conditions are usually thin and small for age. Breathlessness is classified as mild when the child has only chest recession, and there is no contraction of sternocleidomastoid or nasal flaring and severe when all three are present Microcephaly can be associated with some of the intrauterine infections and genetic disorders like congenital rubella syndrome and Edwards syndrome Dolichocephaly (increased antero-posterior diameter) is seen in ex-preterms Syndromes with dysmorphic facial features Downs syndrome almond shaped eyes (due to epicanthal folds); Brushfield spots (light colored spots in the iris); small, flat nose; small mouth with a protruding tongue; small, low set ears; round faces; flat occiput Turners syndrome prominent, posteriorly rotated auricles with looped helices and attenuated tragus; infraorbital skin creases; mildly foreshortened mandible Williams syndrome broad forehead; short nose with broad tip; full cheeks; wide mouth with full lips Noonans syndrome downwards slanting eyes with arched eyebrows; epicanthal folds; broad forehead; nose with wide base and bulbous tip; pointed chin Marfans syndrome long, thin face; deep-set eyes; down-slanting palpebral fissures; receding chin; dolichocephaly; malar hypoplasia; enophthalmos DiGeorge syndrome small ears; asymmetric facies; small mouth and chin Malar flush plum coloured malar eminences Hutchinson (conical) incisor is seen in congenital syphilis (patent ductus arteriosus) and enamel hypoplasia in Ellis-van Creveld Syndrome (atrioventricular canal, ventricular septal defect, atrial septal defect, and patent ductus arteriosus). Caries tooth may be a cause of infective endocarditis in congenital heart disease. In preaxial polydactyly, the extra digit is on the radial (thumb) side while in postaxial polydactyly, it is on the ulnar (little finger) side of the hand. Oslers nodes are painful, red, raised lesions found on the hands and feet and is seen in infective endocarditis Janeway lesions are nontender, macular lesions, most commonly involving the palms and soles and seen in infective endocarditis. Splinter hemorrhages appear as narrow, red to reddish-brown lines of blood that run vertically under nails. Splinter hemorrhage can be associated with infectious endocarditis, systemic lupus erythematosus, and trauma OSCE CHECKLIST PRIOR TO THE TASK Washes hands or uses alcohol rub Explains what he/ she is going to do and ask for permission to examine Positions and exposes the child appropriately Makes sure that the room is adequately lit TASK Looks for the following general points General well being Interest in the surroundings Size of the child Degree of breathlessness Environment (Equipment) Looks for the following specific points Head size and shape Face Conjunctiva Mouth Hands and fingers Difference in colour between limbs POST- TASK Makes sure that the child is not left exposed Thanks the child / parent for co operation Task: INSPECTION OF THE CHEST PRIOR TO THE TASK Introduce yourself to the child and carer and ask for permission to examine For inspection, the room should be well lit. Ensure that the lights are turned on and the windows are open The child should be undressed appropriately to the waist. In older child, the examination is easiest to perform while they sit over the edge of the bed or even on a chair Examine the younger child on the parents lap. STEPS OF THE TASK Look tangentially from foot end of the bed in supine patients and from the sides in sitting patients. Look for the following and comment Shape of the Chest symmetrical or asymmetrical Symmetry of chest expansion Scars Pulsations Observe for apical impulse, parasternal, suprasternal, epigastric pulsations. Spine for scoliosis POST- TASK Make sure that the child is not left exposed Thank the child / parent for cooperation VIGNETTE Common asymmetrical chests Pectus carinatum: also called pigeon chest, deformity of the chest characterized by protrusion of the sternum and ribs. It may occur as congenital abnormality or in association with genetic disorders such as Marfans syndrome, Morquio syndrome, Noonan syndrome, Trisomy 18, Trisomy 21, homocystinuria, and osteogenesis imperfecta. Pectus Excavatum: also called funnel chest, deformity of the anterior wall of the chest producing sunken appearance of the chest. It may occur in rickets, Marfans syndrome and spinomuscular atrophy. Harrisons sulcus: horizontal indentation of the chest wall at the lower margin of the thorax where the diaphragm attaches to the ribs. It may occur in conditions with increased pulmonary blood flow or chronic asthma. Scars: lateral thoracotomy scar results from closure of patent ductus arteriosus, tracheoesophageal fistula repair and Blalock Taussig shunt. Central sternotomy scar is seen after open heart surgery and lobectomy. Children can have drainage scars in epigastrium, subclavian/axillary scars from pacemakers and scars following cardiac catheterization in the groin and neck. Pulsations: Apical impulse will be shifted peripherally due to cardiomegaly, collapse of left lung or fluid in the right pleural cavity Parasternal pulsations can occur due to right ventricular enlargement or enlarged left atrium pushing the right ventricle. The most common cause of suprasternal pulsations is dilated aorta due to aneurysm or markedly increased blood flow. Epigastric pulsation may be seen in thin children, right ventricular hypertrophy and abdominal aneurysm. Scoliosis should be looked for in the standing and not in sitting position OSCE CHECKLIST PRIOR TO THE TASK Washes hands or uses alcohol rub Explains what he/ she is going to do and ask for permission to examine Positions and exposes the child appropriately Makes sure that the room is adequately lit TASK Looks tangentially from foot end of the bed in supine patients and from the sides in sitting patients Looks for the following points and comments Shape of the Chest Symmetry of chest expansion Scars Apical impulse, parasternal, suprasternal, epigastric pulsations Spine for scoliosis POST- TASK Makes sure that the child is not left exposed Thanks the child / parent for co operation Task: PALPATION OF THE CHEST PRIOR TO THE TASK Introduce yourself to the child and carer and ask for permission to examine The child should be undressed appropriately to the waist. Position the older child so that they sit over the edge of the bed or lie down on the couch Examine the younger child on the parents lap. Warm your hands for palpation STEPS OF THE TASK Be gentle with palpation Apical Impulse: Place the palm of the whole hand flat over left chest wall to get a general impression of the point of maximal impulse. Next, lay the ulnar border of the hand on the chest parallel to rib space where the impulse was felt and try to locate the apex. Finally palpate with the fingertip of the index or middle finger to localize the apical impulse and define its character. Use the left hand to palpate the carotid artery to time the apical impulse. With the finger of the right hand still in place over the apex beat, palpate the manubriosternal joint (angle of Louis) which is present just below the suprasternal notch and is felt as a prominence with the left hand. It corresponds to the second intercostal space. Slide the index finger and count down the next few intercostal spaces until you locate the intercostals space that is level with the apex beat. Look at the position of the apex with reference to the midclavicular line. If the apical impulse is not readily palpable in the supine position, ask the child to lie on their left side. If the apex beat is not still palpable, try on the right side in case of dextrocardia. Parasternal pulsation and heave: With the fingertips, palpate over the left sternal edge to find the parasternal pulsations. With the child lying in supine position, place a pencil lateral to the left sternal edge and look tangentially for lifting of the pencil. Next, place the base of your hand just lateral to the left sternal edge and palpate for a parasternal heave. If parasternal heave is present, try suppress it by exerting pressure with base of the hand. Thrills are best felt with fingertips. Time the thrill with carotid or brachial pulse. Palpate the following areas. Apex of the heart 3rd to 5th intercostal space along the left sternal border Pulmonary area (left second intercostal space) Aortic area (right second intercostal space) Suprasternal area Carotids POST- TASK Make sure that the child is not left exposed Thank the child / parent for cooperation VIGNETTE Apical impulse is the farthest inferior and lateral maximal cardiac impulse on the chest wall. It results from the heart rotating, moving forwards and striking against the chest wall during systole. Apical impulse is normally felt in the 4th left intercostal space on the midclavicular line. It may be difficult to palpate in obese children and in pericardial effusion. Displaced apex Tension pneumothorax and pleural effusion (push apex away from the lesion) Pulmonary fibrosis and collapse (pull towards the side of the lesion) Left ventricular hypertrophy apex is displaced down and out Right ventricular hypertrophy apex is displaced outwards Skeletal abnormalities Quality of apical impulse (normal apex lifts the palpating fingers briefly) Sustained (increased amplitude and duration) pressure overload (aortic stenosis) Hyperdynamic or forceful (increased amplitude but not duration) volume overload (mitral incompetence and aortic incompetence) Tapping palpable first heart sound of mitral stenosis Parasternal pulsations Palpable 2nd heart sound reflects pulmonary hypertension. Parasternal heave is present in right ventricular hypertrophy or left atrial enlargement pushing the right ventricle. There are three grades of parasternal heave Grade I heave identified by lifting of the pencil alone and not the heel of the hand Grade II easily identified, can be suppressed with pressure Grade III lifts the heel of the hand and cannot be suppressed with pressure Thrill is a palpable murmur that felt like a purring cat. While describing the thrill, describe the site and phase of cardiac cycle. When thrill is present, the accompanying murmur is by definition at least 4/6 in intensity. OSCE CHECKLIST PRIOR TO THE TASK Washes hands or uses alcohol rub Explains what he/ she is going to do and ask for permission to examine Positions and exposes the child appropriately Warms hands before TASK Palpates gently Apical Impulse Places the palm flat over left chest wall to get a general impression Keeps the ulnar border of the hand parallel to rib space Palpates with the fingertip to locate the apical impulse Palpates the carotid artery

The Importance of Improving Communication Skills in the Business World

My biggest challenge while trying to move up the corporate ladder is interpersonal communication with co-workers and presentation speeches in front of the owners and financial managers. During my childhood, I did not have the opportunity to communicate with my parents or examples of loud arguments and negative personal attacks. Humans develop language and social skills from its surroundings so I guess I can blame mine on my dysfunctional family. At least I did almost five years ago. When the Director of Finance promoted me to senior accountant, his only constructive criticism was to attend different communication courses to groom me for the Assistant Director of Finance position. The frustration of feeling misunderstood and being unable to make ourselves understood by another person is my a constant hurdle for me and considered a barrier of communication (anything that blocks the meaning of what is being said) that many humans experience. Great communication can be compared to the way we build our buildings, one brick at a time. The foundation of the house is trust and we develop trust with personal interaction not as a group. It is said that to speak effectively, a person should be open, direct and bold; however, that is what got me into these classes in the first place. The classes teach how to balance finesse and respect with boldness and direct communication. As mentioned earlier, constantly conquering and rising above the barrier of communication. To name some of the barriers that arise daily are stereotyping, language, showing approval or disapproval, and becoming defensive. In my opinion, stereotyping is the biggest obstacle amongst people. Stereoty pe is a label or typecast of another person based on an oversimplifie... ... is an important variable--if there were never any time pressures, collaboration might always be the best approach to use. In addition to time pressures, some of the most important factors to consider are issue importance, relationship importance, and relative power: †¢ â€Å"Issue importance - the extent to which important priorities, principles or values are involved in the conflict. †¢ Relationship importance - how important it is that you maintain a close, mutually supportive relationship with the other party. †¢ Relative power - how much power you have compared to how much power other party has. â€Å" (Whetten 2002) Finally, learning the importance of interpersonal communication and effectively utilizing it daily as part of my normal daily routine, the Assistant Director of Finance in a multimillion dollar hotel is mine, which has been my goal for the last five years

Tok Presentation

Why did we choose this topic? We think that knowing the past is an important thing – to understand what is happening and to prevent the â€Å"same† mistakes from the past. However, there is a slight problem in our knowledge of past. And that’s why we asked this question: †¦.. Real-life situation You might be thinking†¦why did they choose this topic? Isn’t it obvious that what we know really happened? Are they trying to show us some stupid conspiracy theories or what? So here comes the real life situation. It is no made-up situation because, unfortunately, it happened to me recently. I was reading sources for my EE. The second source I read basically overthrew/contradicted my whole research question. I am writing about a ruler in medieval Japan who brought peace which lasted 250 years and how he accomplished this peace. As I read the second source, it stated that the one that actually established the peace was not this ruler, but the one before him. With this newfound information my whole EE practically fell apart. So, I had two contradictory sources and a load of questions: How it could be possible for such a contradicting sources to exist? And how do we know which one is true and which one isn’t? Sources Okay, now let’s get back to our knowledge of past. Where do we get it from? Well, there are different sources that together help us gather our historical knowledge. We can categorize them into two groups: primary and secondary. Well, I hope you all know what primary and secondary sources are, but if you don’t let me say it really briefly. Primary sources are those that were created by people who witnessed the events that are under study and secondary are sources, which are build upon (analyze and interpret) primary ones. Now, let’s try to make a list of the sources so that we can demonstrate how some of them can become unreliable. PrimarySecondary Diaries Journal/magazine article Pottery (physical stuff)History textbook for schools LettersBook about history InterviewsEncyclopedias SpeechesReviews Documents Photographs Now that we have a list of sources, we need to think about what could possibly affect them. Those can be all four of our tools of knowledge – perception, emotion, reason and language. Using these, we? ll show you how the sources can reflect the past not very accurately. Let’s start with primary sources. What can affect them? Let’s start with written accounts and diaries. First, the writer must perceive the event. What can go wrong in perception? Well, each person perceives things selectively, according to what they expect to see, according to their emotions, culture, traditions and so on. Let’s imagine a soldier named Joe. After surviving a battle he writes a letter to his wife. I believe I do not have to mention that this letter will later become a primary source for us. It consists of many emotional sentences about the death of John, Joe’s friend, who died during the battle and there is only little information about the battle itself and its outcomes. This shows us already, that Joe perceived very little from the battle, but instead concentrated on what was happening to his friend (which is natural, but for historians that are studying the battle rather unfortunate. However, Joe describes something from the battle. He says that their enemy‘s ranks consisted of thousands of soldiers compared to their barely thousand. However, other sources from the same battle state, that the armies were equal in numbers. So, obviously, Joe exaggerated as people tend to under stress situations. But his wife will never know this bit of information Furthermore Joe writes that it was the enemy who actually provoked the battle, while source written by someone from the other side states that is was the exact opposite. So obviously nobody wants to admit to be the aggressor. This was just an example of how perception and reason can influence the given account of an event from the past. Now let’s watch a little video. I hope you know the guy that will be show in it 😉 So, what can we say about some speeches of politicians or propagandistic films or pictures? These also count as primary sources, however I think it is obvious why they cannot be very reliable. Their purpose is to manipulate and distort the truth. For us, and for historians, sometimes it might be very hard to distinguish whether something is a propaganda and manipulation of facts or whether it is not. It is essential for the historians and us to be able to distinguish what is propaganda or manipulation and what is not. Even though such sources contain manipulated information which is useless for historians who want to know the truth, they are still valuable since they help us understand the historical context of that time. Furthermore data and official documents can also contain manipulated information and that is even harder for us to see, because we tend to believe â€Å"official† things. To get back to our knowledge issue, knowledge of the past that we gain from primary sources can be inaccurate, since primary sources tend to be very subjective. But there are plenty of orimary sources, which give us an objective and therefore probably accurate account of the past, such as photographs, data and official documents (if they are not manipulated). Excluding the fact that they can be misleading, without primary sources, we would be practically lost, since it is thanks to them that we have got at least some information about the past. Secondary sources: Now let’s move to secondary sources. The most widely â€Å"used† secondary source are historians and textbooks they write. Historians are very important for us, receivers of the knowledge. Why? If we only had primary sources, we would be lost. First, they are sometimes very hard to understand (especially if they are in a language you don’t speak 🙂 and also there can be overwhelming number of them and we then might not be able to distinguish the important ones from the ones that contain no valuable information. That’s where historians come in handy. They gather the information, read through as many sources as possible, interpret the information included and then write books that should be understandable for us. But, there are several problems. The first, maybe not the obvious one, is that historians do not always get all the information they need to give an account of a particular event. It’s like a puzzle. They have many pieces, but sometimes the pieces don’t fit together or there are some pieces are missing. Then they have to throw the odd ones out and they might find out that even more pieces are missing. Then they have to fill in the gaps themselves. This â€Å"filling in the gaps† can be very dangerous, especially if the historians are biased. Quite often historians are nationally biased. They have been raised in one country along with its traditions and culture and therefore, even if they are trying their best, they are going to write the history from their country’s point of view. Another problem comes in understanding the primary sources. The main obstacle in this case is language, which might have been rather different at that time. As much as historians may try, the translation can almost never be perfect. Sometimes those are just minor mistakes that don’t matter, but in some cases, the translation might be fatal. However, we will never know whether the translation was wrong or not. Furthermore, these sources can be further translated, so we basically get a translation of translation and the source can completely lose its original meaning. To conclude and get back to our question, even though (we hope) they are trying to be as objective as they can, historians can make mistakes in â€Å"filling the gaps†, in being nationally biased and in the translation of the sources. However, their role in our knowledge of past is essential, since they put all the pieces of information into a meaningful whole. Now let’s look at us. We are the receivers of knowledge. Since our own knowledge of past is way more limited than the knowledge of historians, we are more prone to making wrong conclusions from primary sources. Because of this same factor, we might also overlook some vital points. Also, have you ever thought about checking whether a certain historian is telling the truth? Or did you just blindly believed everything he said, just because he has the title of historian? This is a typical ad hominem fallacy that we all can make. Lastly, we, similarly as historians, are nationally biased, which also â€Å"clouds† our reasoning. Final Conclusion To conclude our presentation, we should now see that we know our past only to a certain extent. It depends on the reliability and amount of the primary and secondary sources that we have. We also need to be aware of the biases or drawbacks of the primary and secondary sources in order to distinguish the biased or manipulated sources. In the future, we might have a better knowledge of past, since new and new sources are discovered every day. And, what do you think Jarka did with her EE sources? She was kinda hopeless at first, but then she decided to read the remaining sources. The rest, supported her research question (thankfully), so she could conclude (with almost 100 % certainty) which one was the one that was not true. ? Also, primary sources serve the purpose of the writer and were not written to become parts of textbooks in the future. P. S. do not have to reflect truth, but rather a ‘personal’ truth. Often we do not have written accounts from peasants and lower classes, simply because they didn? know how to write, didn? t consider it necessary, useful†¦ CONCLUSION =our knowledge of past is in many cases not the same as the past itself, because it is based on human interpretation of why and how certain events happen = also, new evidence is constantly being found and it might completely change our view of what and why happened = also new technologies are invented =thus we can say that past is stil l alive and changing†¦ = try to gather as much different sources as u can- compare them†¦ do what historians do†¦.

Mental Health Disorder Major Depressive Disorder

Mental Health Disorder: Major Depressive Disorder Christine C. Nguyen California State University, Dominguez Hills Professor Chun-Wetterau Mental Health Disorder: Major Depressive Disorder A disabling, painful, and costly mental disorder that can affect adults, teens, and children in debilitating ways; this is how Major Depressive Disorder (MDD) is viewed. Depression stems from a mixture of nature and nurture; it is compiled with factors such as genetics, socio-cultural, environment, and psychology (Marsella, 2003). It is important that clinicians, social workers, health care providers, and those that provide care and service of others recognize the symptoms of MDD and know the forms of treatment for this disorder. The history of depression reaches back into ancient Mesopotamian times depression was first labeled melancholia (Nemade, Reiss Dombeck, 2007). During this period, people were certain that melancholia was caused by supernatural possession. Thus, the initial documented perception of depression was that is was a spiritual or mental sickness, and not a somatic one (Nemade, et al., 2007). The view of depression as a spiritual or mental illness stayed this way until the 19th and 20th century (Nemade et al., 2007). In 1950, scientists started looking for more organic causes of depression and divided the disorder into subtypes based on what was believed to have caused the disorder (Nemade et al., 2007). Today, MDD is commonly misinterpreted as depression,Show MoreRelatedMajor Depressive Disorder And Major Depression1540 Words   |  7 PagesMajor Depressive Disorder and Major Depressive Episodes affect many across the country in various forms and degrees.
