Created by

turbulence in a fluid column passing through an incompetent valve, or from a vessel of smaller caliber to a larger. The larger the orifice the bigger the thrill. Also by sharp firm percussion on one part of the abdomen and feeling a shock wave over a distant part of the abdomen—the so-called fluid wave.]

Vital Signs Checklist: Pulse, Blood Pressure [B/P], Respiration [R], Temperature 1. Pulse:

a) Locations: Arm [Antecubital Fossa]: Brachial artery Forearm: Radial & ulnar arteries Groin: Femoral artery Popliteal fossa: Popliteal Ankle: Posterior tibial Foot: Dorsalis pedis Neck: Carotid Thorax: Apex of the heart

b) Radial pulse assessment: i) Technique: If distal pulse not felt palpate next proximal pulse, Palpate radial artery w/ pulp of index & middle fingers 2

fingers widths proximal to crease of the wrist [vary pressure to feel for strong pulse] & count for 1minute ii) Report: Rate, Rhythm, Character [amplitude & contour], Rigidity of vessel [best done through Osler’s maneuver during

BP measurement] (1) Rate:

Normal: Normal 60-100 [140 in babies] Tachycardia: >100 [usually accompanies fever] Bradycardia: < 60 (2) Rhythm: Use EKG to determine rhythm if abnormal rate

Regular: Don’t use “normal” Regular irregularity: Premature atrial/ventr contraction Irregular irregularity: e.g. atrial fibrillation (3) Character of pulse: Consists of contour & amplitude Best observed in right carotid artery (4) Amplitude: Crude indication of stroke volume rated from 0-4

0: Absent, not palpable 1: Diminished, barely palpable 2: Normal [expected] 3: Full & increased (a) 0/1 Heart failure or Increased peripheral resistance (b) 4 [Hyperdynamic circulation] Increased stroke volume [e.g. aortic regurgitation, aretriovenous fistulas, or

patent ductus areteriosis], Decreased peripheral resistance, Decreased compliance [arteriosclerosis] (5) Contour [Waveform]: SPEED of the upstroke, the duration of the SUMMIT & the SPEED of the down stroke, Note

the effects of exercise, exertion, or breathing on the pulse Pulsus alternans: Alternating weak & strong beat [Left ventricular failure that is usually accompanied by left sided S3]

Pulsus bisferiens: Biphasic pulse, 2 Strong systolic beats separated by mid systolic dip, AS+AR [Pure aortic regurgitation, Aortic stenosis combined w/ regurgitation, & though not often palpable hypertrophic cardiomyopathy]

Pulsus bigeminal: May masquerade as pulsus alternans [Normal beat alternating w/ premature contraction]

Pulsus paradoxus [misnomer]: Exaggeration of normal fall in amplitude during inspiration, Systolic BP drop >12-15mmHg, [Severe airway obstruction [e.g. severe asthma, emphysema], Precardial tamponade, Constrictive pericarditis]

Water Hammer Pulse/Corrigon pulse [collapsing pulse]: Greater amplitude, Rapid rise [upstroke], Normal summit, Sudden descent [due to backflow through aortic valve], A pulse that suddenly collapses [Aortic regurgitation, or Patent ductus arteriosis]

c) Pulse deficit assessment: It is the difference between the heart rate by auscultation & peripheral rate by palpitation or radial pulse [A difference &/or rapid or irregular rhythm e.g. atrial fibrillation]

d) Radio-femoral delay: Is a delay between the time it takes for a pulse wave to reach the radial artery & femoral artery & is assessed by palpating the radial & femoral arteries at the same time i) Normal transmission of pulse wave to radial is 75ms & 70ms to femoral ii) If a delay exists measure upper & lower extremity blood pressure in supine position iii) Radio femoral delay indicates Leriche’s syndrome Aorta or iliac atherosclerosis, Coarctation of aorta after the

subclavian artery, etc. e) Symmetry assessment: Done by assessing on the left & right hand sides of the body at the same time & same location and can

be assessed at any of the pulse locations. If there are differences in pulses between sides it may indicate local stenosis or compression in the path of the weaker pulse

2. Blood Pressure: Done with sphygmomanometer & stethoscope a) Different pressure readings:

i) Systolic: Maximal pressure in the aorta during left ventricular contraction ii) Diastolic: Lowest pressure in the aorta before left ventricular contraction iii) Mean arterial pressure [MAP]: Normal is 93mmHg, Can be estimated by DP + 1/3 (SP-DP) iv) Auscultatory gap: Silent interval between diastolic & systolic reading Might lead to underestimation of systolic BP

that can be obviated by first determining pressure by palpation v) Blood pressures: When systolic & diastolic fall under different readings use the higher category

4

Classification Systolic [mmHg] Diastolic [mmHg] Hypotension <80 Normal <120 <80 Pre-Hypertension 120-139 80-89 Hypertension Stage 1 [malignant] 140-159 90-99 Stage 2 [malignant] !160 100! Isolated systolic !140 <90 Isolated diastolic !140 >90

vi) Hypotension classifications: <80 mmHg Systolic (1) Relative: In light of past readings (2) Absolute: Symptoms & signs of low BP exist (3) Orthostatic: Fall of 20mmHg systolic 10mmHg diastolic on standing for 3min after recumbency

b) Preparation: i) Patient prep: Rest for 5 minutes, Ask about consumption of caffeine, HTN medications, etc., Use are free of fistulas,

lymphedema, or severe scarring, Patient preferably seated, Preferably remove clothing from are being used ii) Cuff size:

(1) Sizes: Normal adult, Thigh, Pediatric, Babies (2) How to determine: Length of bladder cuff should be 80% of circumference of the upper arm, Width of bladder

should be 40% of arm circumference iii) Cuff placement: Center arrow overlying the brachial artery above the elbow [lower 1/3 arm], Tighten cuff so that it fits

over the arm, Loose cuff will give falsely HIGH B/P reading iv) Patient positions:

(1) Sitting: Normal position & is done with arm @ level of heart, False BP ELEVATION if arm is not supported. Other positions

(2) Standing: Is done to check for orthostatic hypotension or autonomic insufficiency [e.g. diabetes, adrenal insufficiency], is suspected. Wait at least 1 minute after the patient stands before taking this blood pressure & be sure the arm is at heart level when taking it. If there is a drop of >20mmHg on standing wait then the patient has orthostatic hypotension

(3) Supine: c) Technique:

i) While palpating radial or brachial artery inflate cuff until pulse is no longer palpable [note this reading] & add 30mmHg (1) Note whether the artery is still palpable [Osler’s maneuver], if it is that is called a positive Osler’s sign & is

indicative of arteriosclerosis ii) W/ stethoscope [use bell if not audible w/ diaphragm] over the brachial artery in the ante cubital fossa & reinflate cuff to

higher level iii) Deflate the cuff at rate of 2-3mm/sec [to avoid venous congestion wait 15seconds before reinflating] iv) While listening with stethoscope note when 1st 2 consecutive beats heard [systolic] v) When sounds disappear that is diastolic BP vi) If BP is abnormal confirm by repeating 2 or 3 times

d) Complications: i) Anxious patient: Causes BP elevation, Take 2 or more readings @ two or more visits ii) Beats not audible: Make sure cuff is right, Use bell, Be sure patient is stable & not hypotensive iii) Arrhythmias: Variation in BP reading [makes them unreliable], Deflate cuff slower than norm, Take several readings &

take average 3. Respiration: Requires a clock with a second hand

Posterior locations [Perform in 3 locations]: 1. Above scapula 2. Between scapula 3. Below scapula

9. Auscultation & Percussion: a) Locations:

Anterior locations Posterior locations b) Percussion: Means to tap the surface to determine underlying structures. Sounds travels to the underlying tissues through

chest wall and reflects back & is picked up by the examiner. Different areas produce different sounds. Over heart & solid organs the sound is dull. i) If right handed, place the middle finger of the LEFT hand on the surface you are going to percuss, this is known as the

pleximeter finger. ii) Middle finger of right hand you tap with your plexor finger. iii) Movement is at the wrist

18

iv) Technique: v) Sounds: Normally in thorax you will hear resonance [exclude cardiac & liver dullness], Sounds listed below

(1) Flatness or absence: Pleural effusion (2) Dullness: Essentially any condition that decreases the amount of air in the lungs [e.g. Pneumonia, Lung collapse,

Pleural effusion] (3) Resonance: NORMAL (4) Hyperresonance: Essentially any condition that increases the amount of air trapped in the lungs [e.g. Emphysema,

Pneumothorax Chronic bronchitis], Normal cardiac dullness may ALSO disappear (5) Tympany: Gastric air bubble, Large pneumothorax

vi) Diaphragmatic excursion: Can be used to find level of diaphragm during inspiration & expiration by listening to changes in percussion [it will become dull when you get to the diaphragm] (1) Percuss chest during expiration starting from the tip of the scapula & working down [mark the level] (2) Percuss again during deep inspiration starting from the tip of the scapula & working down [mark the level] (3) The distance between the two points should normally be 4-6cm (4) Measure on both front & back (5) The distance will be decreased in phrenic nerve paralysis & pleural effusions

iv) Breath Sounds: Generally breath sounds will be INCREASED in regions of consolidation

19

(1) Continuos: Wheezing [high-pitched continuous, musical sounds heard in respiratory diseases.] or Rhonci [low-pitched coarse rattling sound somewhat like snoring, usually caused by secretions in bronchial airways], Musical prolonged

(2) Discontinuous/Intermittent: Crackles or Rales [discontinuous, intermittent, nonmusical and brief sounds in respiratory and cardiac diseases]

(3) Fine/coarse: Pleural rub [Grating sounds during inspiration and expiration], Nonmusical brief: (4) Reduced or absent: Essentially any condition that will reduce the amount of air entering & exiting the lung [e.g.

Pneumothorax, Pleural effusion, Emphysema, Lung collapse, Chronic bronchitis] v) Bronchopony: The patient is requested to repeat a word several times (the numbers "ninety-nine" or "sixty-six" are

traditional) while the physician auscultates symmetrical areas of each lung. Normally, the sound of the patient's voice becomes less distinct as the auscultation moves peripherally; bronchophony is the phenomenon of the patient's voice remaining loud at the periphery of the lungs or sounding louder than usual over a distinct area of consolidation (such as pneumonia). This is a valuable tool in physical diagnosis used by medical personnel when auscultating the chest.

vi) Whispered pectorliquy: Ask patient to whisper “99” & listen for low pitched & indistinct sounds. When it is whispered sounds are usually NOT heard. If you hear sounds it indicates a region consolidation.

vii) Egophony: Ask patient to say ‘ee’ & you will normally hear a muffled long E. If what is heard is a higher pitched sound that sounds like the letter "a." (Some doctors refer to this as "e to a changes."). This indicates a region of consolidation [e.g. pneumonia].

Eye Examination 1. Anatomy:

a) 2. Initial Assessment: With the patient seated facing the examiner at about two feet away at the same level

a) Examine the eyes and orbits: Size, Shape, Symmetry, Scars, Swellings. i) Periorbital edema Where edema due renal failure first manifests

b) Eyebrows for hair: Distribution & Lesions i) Loss of the lateral one third: Suggests Hypothyroidism, Leprosy, or Myxedema

c) Shine the penlight at the eyes directly from about two feet: i) Assess the symmetry of the highlights reflected from each cornea ii) Reflection should be in the nasal field of each eye If it is not then this indicates an extraocular muscle dysfunction

3. Eyelids: Check the eyelids for, Position, Swelling, Redness, & Lesions a) Position: If lowered then ptosis Indicative of Horner’s syndrome b) Exopthalamos Indicative of hyperthyroidism [it is observed from above] c) Eye lashes: Top lid has 2 rows & bottom lid has 1 row d) Direction: Ectropion [eye lid turned out] & Entropion [eye lid turned in] e) Cant close: Facial nerve palsy f) Can’t open: CN III nerve palsy g) Lesions:

Chalazion: Beady nodule in either eyelid caused by chronically inflamed meibomian gland

Sty: A pimple like infection around a hair follicle near the lid margin

Blepharitis: Inflammation of eyelids making them red, irritated, itchy, & formation of dandruff-like scales on eyelashes.

h) Xanthelasma: Sharply demarcated yellowish collection of cholesterol underneath the skin, usually on or around the eyelids

i)

21

4. Conjunctiva: Pull the lower eyelid down and assess the palpebral (palor) and bulbar conjunctiva (hemorage) for Color, Pigmentation, Swelling, Inflammation, & Growths such as a pingueculum or a pterygium a) Color: If excessively pale Indicates anemia

Pingueculum: A yellowish patch or bump on the white of the eye, most often on the side closest to the nose. It is not a tumor, but an alteration of normal tissue resulting in a deposit of protein and fat. Unlike a pterygium, a pingueculum does not actually grow onto the cornea. A pingueculum may also be a response to chronic eye irritation or sunlight.

Pterygium: A fleshy growth that invades the cornea. It is an abnormal process in which the conjunctiva (a membrane that covers the white of the eye) grows into the cornea. Pterygium may be small or grow large enough to interfere with vision, and commonly occurs on the inner corner of the eye. The exact cause of pterygium is not well understood. Pterygium occurs more often in people who spend a great deal of time outdoors, especially in sunny climates. Long-term exposure to sunlight, especially ultraviolet (UV) rays, and chronic eye irritation from dry or dusty conditions seem to play an important causal role.

Chemosis: Swelling of the tissue that lines the eyelids and surface of the eye (conjunctiva).

Subconjuctival hemorrhage:

5. Lacrimal Apparatus:

Anatomy: Sjogren's syndrome: Dacryocystitis: Epiphora:

Sjögren's ("SHOW-grins") syndrome is a chronic disease in which white blood cells attack the moisture-producing glands

Infection of the tear sac between inner corner of eyelids and nose. Usually caused by block of the duct that carries tears from the tear sac to the nose. Dacroadenitis is lacrimal gland enlargement.

An overflow of tears, usually caused by poor drainage of the tear film from the eye. Most common cause is block of lacrimal ducts. May also result from excessive tearing.

a) Method: i) Look at the upper lateral orbital margin for any swelling of the lacrimal gland ii) Check puncta on the medial end of each upper & lower lid for Inflammation, Regurgitation of fluid, Blockage. iii) Press on each side of the nose for evidence of blockage or inflammation in the nasolacrimal sac.

6. Anterior Chamber: Shine the light across the cornea tangentially to look for the highlight and shadow of any corneal opacity and for the crescentic shadow of a shallower than normal anterior chamber. a) Sclera:

i) Episcleritis: Is a relatively asymptomatic acute onset redness in one or both eyes. Typically, you'll observe a sectoral injection of the episcleral and overlying conjunctival vessels, although the redness may be diffuse throughout these

22

tissues. Occasionally, there may be a translucent white nodule centrally within the inflamed area (nodular episcleritis). While some patients complain of mild pain or tenderness to the affected region, particularly upon manipulation, often there is no associated discomfort. The cornea remains clear in this condition, although long-standing or recurrent episcleritis may lead to dellen formation. There is no associated anterior chamber reaction.

ii) Jaundice- look for yellow. Tell patient to look down WHILE holding upper eyelid b) Cornea: Ensure it is clear, Without lesions, opacities, & abnormality. VIEWED FROM THE SIDE WITH PENLIGHT.

Looking for a bulge i) Arcus senilis: Grayish or whitish arc or circle visible around the peripheral part of the cornea in older adults. Arcus

senilis is caused by lipid deposits in the deep layer of the peripheral cornea and not necessarily associated with high blood cholesterol. (1) Should always indicate to the physician the need to explore the possibility of alcoholism, particularly when it is

detected in males under the age of 60.

(2) ii) Keratitis: Infection or inflammation of the cornea (the centre portion of the eye that surrounds the pupil) & is usually

accompanied by eye pain, photophobia, foreign body sensation, tears, & blurred vision. c) Iris:

i) Inspect: For Color and Uniformity, Nodules, Vascularity of the surface of the iris, Look for any coloboma, & Any corneal arcus [if occurs in elderly individuals known as arcus senilis & is pictured above].

ii) Iritis: Inflammation predominantly located in iris. More correctly classified as anterior uveitis. Ciliary body can also be inflamed and is called iridocyclitis.

(1) iii) Increased iris vascularity Indicates diabetes

d) Pupil: Check the shape, size, symmetry and regularity of each pupil. i) Pupillary reflex

ii) Reflection: Check for any light being reflected in the pupil from a cataract or (in children especially) from a retinoblastoma.

es: With one hand blocking transmission of light to the opposite eye shine the penlight into each pupil, coming in from the side, and assess the direct and consensual reflex on each eye.

iii) Accommodation reflexiv) Adie’s pupil: Widely dilated, Light reflex absent, Near reaction present

: Check the pupillary response on each eye in the accommodation reflex.

v) Argyll-Robertson Pupil: Irregular pupils bilaterally, React to near reaction but not light e.g. syphilis & diabetes vi) Horner’s syndrome: Partial ptosis, Constricted pupil, Anyhdrosis vii) Bilateral dilated pupil Brain damage, Anti-cholinergic poisoning viii) Small fixed pupils Pontine hemorrhage, Opiate poisoning

e) Anterior chamber: i) Anatomy: Circulates aqueous humor, Contains ciliary body through pupil to iridocorneal angle, Drained by canal of

Schlemm ii) Hypaema: Hemorrhage in anterior chamber of the eye iii) Hypopyon: Accumulation of pus in anterior chamber of the eye

23

iv) Technique: v) Narrow angle Indicates glaucoma [increased fluid in anterior chamber due it increased aqueous humor production or

impaired drainage] f) Lens:

i) Cataracts: Opacity that develops in the crystalline lens of the eye or in its envelope

ii) Aphakia: Absence of a lense

7. Extraocular muscles: Check the extraocular eye movements using the four tests.

a) Movements: b) Corneal reflection: Already done c) Convergence: Of the accommodation reflex. d) H test: Starting in midgaze and moving in the horizontal plane until one or two flicks of nystagmus are observed, then the

upward and downward movements of the eye at this lateral position. Cross to the opposite lateral plane and assess the vertical movements once more. Watch during all of this that both eyes remain conjugate throughout.

e) Cover/uncover test: Ask the patient to fix his gaze on an object in the middle distance. Cover one eye. After 20 seconds take the cover away and watch to see if the covered eye has maintained its position. Check the opposite eye the same way.

f) Lateral deviation, Ptosis, Dilated pupil Occulomotor nerve [CN IV] palsy g) Inability to look down Trochlear nerve [CN IV] palsy h) Medial deviation of the eyeball Abducens nerve [CN VI] palsy i) Strabismus: Condition in which a person can’t align both eyes simultaneously j) Exotropia: Divergent eyeballs k) Esotropia: Convergent eyeballs l) Squint: Either paralytic or non-paralytic m) Nystagmus

i) Horizontal e.g. Cerebellar lesion, Brain stem lesion, Drugs [e.g. ethanol & phenytoin] ii) Vertical e.g. From inner ear, Vestibular disease, Brainstem disease, PCP

8. Visual acuity: Position your patient 20 feet from the Snellen’s chart. Cover each eye in turn. Get the patient to read the lowest line on the chart possible. If the patient reads the line correctly, ask them to try the next line. When the lowest line the patient can read is reached, the line is counted if the patient accurately identifies greater than 50% of the letters. Check the vision finally with both eyes uncovered. a) Myopia: Near- or short-sightedness, is a refractive defect of the eye in which collimated light produces image focus in front

of the retina when accommodation is relaxed. See nearby objects clearly but distant objects appear blurred. b) Hyperopia [hypermetropia]: Farsightedness or longsightedness, is a defect of vision caused by an imperfection in the eye

(often when the eyeball is too short or when the lens cannot become round enough), causing inability to focus on near

24

objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. People with hyperopia can experience blurred vision, asthenopia, accommodative dysfunction, binocular dysfunction, amblyopia, and strabismus.

c) Presbyopia: Eye exhibits a progressively diminished ability to focus on near objects with age. d) Astigmatism: When an optical system has different foci for rays that propagate in two perpendicular planes. If an optical

system with astigmatism is used to form an image of a cross, the vertical and horizontal lines will be in sharp focus at two different distances.

9. Visual field: Sit facing the patient at the same level two feet away. a) Testing Temporal field:

i) Assess the temporal field of both eyes by asking the patient to indicate when he/she sees your moving fingers as you move them forward from behind the lateral margins of the orbits in the horizontal plane and the upper and lower lateral quadrants.

ii) If one eye sees your fingers at a significant distance before the other, assess each eye separately to ensure that there is no cortical extinction in the weaker eye.

b) Testing Nasal field: Then cover one of your eyes and ask the patient to cover their opposite eye (ie the patient’s right eye and the examiner’s left eye). Assess when the patient sees you fingers in both vertical planes and in the horizontal and upper and lower nasal quadrants. This test assumes that the examiner’s field of vision is normal.

b) Normal retina: Disk color is yellowish/orange/white, Disc vessels are tine, Disk margins are sharp c) Method:

i) Set the lens to the examiner’s acuity correction ii) Place the instrument in front of one eye with the cushioned bar firmly against the upper eyebrow. iii) Hold it with the ipsilateral hand and have the index finger extended so that it is able to control and change the lens easily. iv) Start about three feet from the patient. v) Examine the same eye as you are using. (The patient’s right eye is examined by the examiner’s right eye with the

instrument held in the examiner’s right hand). vi) Observe the RED REFLEX in the pupil of the patient’s eye [if absent then cataract, corneal scarring, retinoblastoma] vii) At an angle of approximately 15 degrees from the sagittal plane approach the patient’s eye until a blood vessel is seen. viii) Focus until this vessel is clear. ix) Follow it to the optic disc. x) Observe the DISC [outline, color, & look for white/pigmented crescent rings] and CUP [cup/disk ratio]. xi) Follow the vessels to each of the four quadrants of the retina. xii) Observe the ARTERIES, VEINS and retinal background.

Arterioles Veins Color Light red Dark red Size Smaller Larger Light reflex Bright Absent

xiii) When this is completed, ask the patient look into the light. xiv) Observe the macula and fovea.

d) Clinical correlations: Drusen: Look like specks of yellowish material under the retina. They are deposits of extracellular material that accumulate between the retinal pigment epithelium (RPE). A few small drusen normally form in the human eye, usually after age 40.

Colobama: Is a hole in one of the structures of the eye, such as the lens, eyelid, iris, retina, choroid or optic disc. Present from birth. A coloboma can occur in one or both eyes.

Glaucoma: Involving loss of retinal ganglion cells in a characteristic pattern of optic neuropathy. Although raised intraocular pressure is a significant risk factor for developing glaucoma, there is no set threshold for intraocular pressure that causes glaucoma.

Hypertensive retinopathy: 1st stage: Copper wiring, Silver wiring 2nd stage: Areterioveinous nicking 3rd stage: Hemorrhages [flame shaped], Exudates that are hard or soft [cotton wool] 4th stage: Papilledema & Hemorrhages [flame shaped]

n) Heart block: Sometimes the signal from the heart's upper to lower chambers is impaired or doesn't transmit. This is "heart block" or "AV block." This does not mean that the blood flow or blood vessels are blocked. Heart block is classified according to the level of impairment — first-degree heart block, second-degree heart block or third-degree (complete) heart block. i) First-degree heart block:

(1) First-degree heart block, or first-degree AV block, is when the electrical impulse moves through the AV node more slowly than normal. The time it takes for the impulse to get from the atria to the ventricles (the PR interval) should be less than about 0.2 seconds.

(2) If it takes longer than this, it's called first-degree heart block. (3) Heart rate and rhythm are normal, and there may be nothing wrong with the heart. (4) Certain heart medicines such as digitalis (DIJ'ih-TAL'is) can slow conduction of the impulse from the atria to the

ventricles and cause first-degree AV block. Also, well-trained athletes may have it. (5) Generally, no treatment is necessary for first-degree heart block.

ii) Second-degree heart block: In this condition, some signals from the atria don't reach the ventricles. This causes "dropped beats." On an ECG, the P wave isn't followed by the QRS wave, because the ventricles weren't activated. There are two types: (1) Type I second-degree heart block, or Mobitz Type I, or Wenckebach's AV block: Electrical impulses are delayed

more and more with each heartbeat until a beat is skipped. This condition is not too serious but sometimes causes dizziness and/or other symptoms.

(2) Type II second-degree heart block, or Mobitz Type II: This is less common than Type I but generally more serious. Because electrical impulses can't reach the ventricles, an abnormally slow heartbeat may result. In some cases a pacemaker is needed.

iii) Third-degree heart block: (1) Complete heart block (complete AV block) means that the heart's electrical signal doesn't pass from the upper to the

lower chambers. When this occurs, an independent pacemaker in the lower chambers takes over. The ventricles can contract and pump blood, but at a slower rate than that of the atrial pacemaker.

(2) These impulses are called functional or ventricular scope beats. They're usually very slow and can't generate the signals needed to maintain full functioning of the heart muscle. On the ECG, there's no normal relationship between the P and the QRS waves.

(3) Complete heart block is most often caused in adults by heart disease or as a side effect of drug toxicity. Heart block also can be present at — or even before — birth. (This is called congenital heart block.) It also may result from an injury to the electrical conduction system during heart surgery. Complete heart block may be a medical emergency with potentially severe symptoms and a serious risk of cardiac arrest (sudden cardiac death). If a pacemaker can't be implanted immediately, a temporary pacemaker might be used to keep the heart pumping until surgery can be performed.

Examination of the Lymphatic System 1. Anatomy: Cervical nodes described in section on head & neck

2. Lymphatic system examination: Inspection of the upper and the lower extremities observing any obvious swellings. Axillary lymph nodes: Inspection: Inspect the axilla, you may see swelling Patient position: Usually patient is seated or reclined for this examination. Examiner tends to raise the patient’s arm, and using the left hand for the patients right axilla, (and vice versa) the examiner passes their extended fingers high into the patient’s axilla. The patient’s arm is now brought to rest on the examiners forearm. Now the examiner should palpate for the following. Every effort should be made to feel for nodes in each of in each of the nodes shown in the image below.

1. Central (push up deep into axilla)

2. Lateral (humoral) 3. Anterior (Pectoral)

4. Infraclavicular (subclavian)

Inguinal lymph nodes: Two groups of inguinal lymph nodes. The horizontal group lies below the inguinal ligament and the vertical group lie along the upper portion of the saphenous vein. Patient position: Have the patient reclined on the couch for this assessment. You will need to expose the groin area. Palpation: Now feel around the inguinal ligament area and along the femoral vessel area. Note that small nodes can be commonly detected in otherwise normal patients.

arteries are punctured. If there are signs of arterial insufficiency in either artery then that arm can’t be used. i) Palpate the radial and the ulnar pulses ii) Ask the patient to make a fist and then occlude the two arteries with pressure iii) Have the patient open his/her hand (the hand should be pale) and release one of the vessels. iv) Watch for a flush of color returning to the hand (within 3-5 seconds). v) Repeat this test releasing the other artery.

6. Lower limb: Be sure to compare limbs a) Inspection:

i) Ulcers/Gangrene: Particularly around medial malleolus & on soles of feet [arterial insufficiency] ii) Veins: Pattern, Varicosities [large dilated veins indicative if venous disease] iii) Swelling: Assess for pitting edema [venous disease] on dorsum of foot posterior to medial malleolus & anterior to the

41

ii) Raise both the legs to approximately 60° iii) Have the patient wiggle his/her toes and maintain in this position for 1 minute. iv) At this point the limbs should be pale v) Have the patient then sit up and swing his/her legs over the side of the bed. vi) Observe the feet: Looking for color returning and the vessels filling. The color should return within 10 seconds and the

veins should fill within 15 seconds. g) Deep vein thrombosis:

h) Varicose vein assessment: i) Manual compression test:

(1) Inspect the lower extremities finding a varicosity & attempt to map out the course of the varicose vein. (2) Place both hands on the vein approximately 10 cm apart & trap a column of blood between fingers of your two

hands. (3) While continuing to compress the vessel first tap with the lower hand feeling for the transmission of a wave to the

upper hand, this ensures that both hands are placed on the same vessel. (4) Next tap with the upper hand feeling for a wave transmission to the lower hand. Remember that the valves in the

veins are unidirectional (blood should only flow from the lower extremity upwards towards the heart). (5) If you are able to feel the transmission of the wave from the upper hand to the lower hand this verifies that the

superficial valves of the vein are incompetent. ii) Trandelenberg’s test:

(1) Have the patient lie on the bed. (2) Raise one leg to 90 degrees and have the patient wiggle his/her toes (emptying the vessels of the extremity). (3) Have the patient remain like this for approximately 60 seconds. (4) Tie the tourniquet around the upper thigh (tight enough to occlude the superficial vessels but not the deep vessels of

the leg). (5) Have the patient stand up & observe the leg for venous filling. (6) If you see immediate venous filling then there is incompetence of the valves of the communicating vessels

(remember that the superficial vessel is still occluded by the tourniquet). (7) Observe the leg for 20 seconds and then release the tourniquet and observe again. (8) Rapid filling of the vessel at this point indicates that there is incompetence of the valves of the superficial vessel.
