What is the correct order for auscultating cardiac sounds?
1. Note the rate and rhythm
Sinus arrhythmia-↑w/inspiration, ↓ w/expiration
Test for Pulse deficit = Auscultate apical rate while palpating radial pulse. The two should be in sync; if not then pulse deficit which indictes weak ventricles, ie Afib, PAC/PVC (Premature Atrial/Ventricular Contraction), heart failure.
2. Identify S1.
3. Identify S2.
S1 is louder than S2 at the apex
S1 coincides with carotid artery pulse
S1 coincides with R wave on ECG.
4. Listen for extra heart sounds
5. Listen for murmurs
What is a pericardial friction rub?
