5 finger method
1) history
2) physical
3) eck
4) Xray
5) lab tests
Physical
- inspection
- JVP
- precordial palpation
- percussion
- auscultation-heart sounds
- grading system of murmurs
- ecg
- x rays
- lab tests
Proper physical exam sequence
1) inspection
2) palpation
3) percussion
4) auscultation
- quiet rooms
- listen on bare skin
- sitting, supine, left lateral decubitus, leaning forward, standing
S1
- mitral and tricuspid closure
- beginning of ventricular systole
S2
- aortic and pulmonic closure
- marks end of systole, beginning of diastolic
Palpation and Percussion
- point of max impulse: 4th and 5th intercostal space at mid clavicular line
- estimate cardiac size when PMI not detectable
- start far left and move medial to find cardiac dullness
JVP
- reflects activity of right side of the heart
- level of JVP visibility gives an indication of the right atrial pressure
- internal jugular is better than external jugular
- normal JVP: 0-9cm
- most common cause of an elevated JVP is an elevated right ventricle diastolic pressure
A Wave
- right atrial contraction
- tricuspid open
- coincides with S1
- precedes carotid pulsation
- giant wave seen in: obstruction between RA and RV, increased pressure in RV, pulmonary hypertension, recurrent pulmonary emboli, A-V dissociation (complete heart block)
C Wave
-backward push by closure of tricuspid during isovolumetric systole and by impact of carotid artery adjacent to the jugular vein
X wave
- passive atrial filling and atrial relaxation
- blood flows into the right atrium from the cava and closure of tricuspid
- steep X descent in cardiac tamponade and constrictive pericarditis
V wave
- atrial filling
- increasing volume and pressure in RA when tricuspid is closed
- prominent V wave in TR and pulm hypertension
Y slope
- open tricuspid and rapid right ventricle filling
- deep Y in severe TR a slow Y descent suggests obstruction to RV filling
Increased JVP
- SVC obstruction
- severe heart failure
- constrictive pericarditis
- cardiac tamponade
- RV infarction
- restrictive cariomyopathy
Positive HJR (hepatojugular reflux)
- poorly compliant RV (RV failure)
- constrictive pericarditis
- obstructive RV filling by TS or RA tumor
Systole
ventricular contraction, ejection
