CARDIOVASCULAR

OSCE
EXAMINATION
 Imp. points Before starting the examination:
 Confirm patient’s details
 Explain the examination
 Do WIPE:
 Wash your hands
 Introduce yourself
Ask
 for Permission\ensure Privacy\Position the patient at 45°1
 Expose the patient’s chest
 Ask if the patient has any pain anywhere before you begin!
 Remember: always examine the patient from the right side.

What to do What to look for

1. General inspection:
connections
e.g. nasogastric tube, oxygen mask or IV line
Comfortable at rest?  Does he look ill, in pain, has SOB
 Cachectic due to malignancy or severe HF
 syndromes that are associated with specific
cardiac disease + could be recognized by the
patient’s appearance:
-Marfan’s syndrome
-Down’s syndrome
-Turner’s syndrome
Inspect chest Scars, visible pulsations, Pectus excavatum or
Pectus carinatum
Inspect legs Scars, peripheral edema, missing limbs or toes
2. Hands: Hands out + palms
facing downwards
-Ask the patient to place the nails of
their index fingers back to back:
 if healthy you should be able to
observe a small diamond shaped window
(Schamroth’s window)
Look for clubbing
 When finger clubbing is present
this window is lost (Schamroth’s sign)
-causes of CLUBBING:
 Cyanotic congenital heart disease
 Lung abscess
 Ulcerative colitis & chron’s disease
 Bronchiectasis
 Bronchogenic carcinoma
 Infective endocarditis
 Nothing
 Graves

.Why 45 for cardiac examination? Because it’s the usual position in which the jugular venous pressure (JVP) is assessed
+ if the patient has PE and was laid flat, it might increase and impede breathing.

Look for: -linear haemorrhages lying parallel

Splinter haemorrhages to the long axis of the nail.

3.Pulses

Radial pulse Medial to the radius, using forefinger & middle finger
pulps, to assess rate & rhythm

Brachial & carotid pulses To assess volume & character

Check:
Normal, tachycardia or bradycardia?
Rate Pulse deficit1? Afib.

RHYTHM -Regular?
-Irregularly irregular or chaotic rhythm?
 NO pattern detected, e.g. A fib.
-regularly irregular? Sinus arrhythmia (normal
slowing of the pulse
with expiration)
-Bigeminal rhythm?
-Trigeminal rhythm?

Radio-radial delay: A delay is usually due to arterial occlusion by an

6. Praecordium Characteristics helps with the diagnosis
 AUSCULTATION  Timing:
MURMURS Systolic murmurs:
may be pansystolic, midsystolic (ejection systolic) or late systolic.
results from turbulent
flow across valves pansystolic murmur: extends throughout Systole, its loudness
and pitch do not vary during systole
EXAMPLE: mitral regurgitation, VSD.
midsystolic ejection murmur: does not begin right at the first
heart sound; its intensity is greatest in midsystole
EXAMPLE: crescendo–decrescendo murmur in AS
late systolic: MVP
Diastolic murmurs:
early diastolic murmur: decrescendo murmur in AR
(loudest early because this is when aortic artery pressure is highest)
mid-diastolic murmur: MS & atrial myxoma (the tumour
mass obstructs the valve orifice)
PreSystolic murmur:
It’s an extension of the mid-diastolic murmurs of mitral stenosis due to
atrial contraction before systole.
continuous murmurs:
extend throughout systole and diastole, produced when a
communication exists between two parts of the circulation with a
permanent pressure gradient so that blood flow occurs continuously.
Causes: PDA, Coronary arteriovenous fistula in Hemodialysis patients
pericardial friction rub:
caused by movement of inflamed pericardial surfaces; it is a result of
pericarditis. louder when the patient is sitting up and breathing out. It tends

 Area of greatest intensity: the place on the precordium where
murmur is heard most easily is a guide to its origin. But some may radiate

radiate to the carotid arteries
 Loudness and pitch
loudness and harshness of the murmur (and the presence of a thrill)
correlate with the severity

1. Wash your hands and don PPE if appropriate.

2. Introduce yourself to the patient including your name and role.

3. Confirm the patient’s name and date of birth.

4. Briefly explain what the examination will involve using patient-

friendly language.

5. Gain consent to proceed with the examination.

6. Adjust the head of the bed to a 45° angle.

7. Adequately expose the patient’s chest for the examination (offer a blanket to
allow exposure only when required and if appropriate, inform patients they do not
need to remove their bra). Exposure of the patient’s lower legs is also helpful to
assess for peripheral oedema and signs of peripheral vascular disease.

8. Ask the patient if they have any pain before proceeding with the clinical
examination.
