Cardiac Auscultation Sites Study Guide

These flashcards cover key concepts in cardiac auscultation, detailing locations, sounds, clinical tips, and usage of the stethoscope.

Aortic Valve Area

Located at the 2nd intercostal space (ICS), right sternal border; best for hearing aortic valve closure (A2) and aortic stenosis murmur.

Pulmonic Valve Area

Located at the 2nd intercostal space (ICS), left sternal border; best for hearing pulmonic valve closure (P2) and pulmonic stenosis murmur.

Tricuspid Valve Area

Located at the 4th–5th intercostal space, left sternal border; best for hearing tricuspid murmurs, right-sided S3 and S4.

Mitral (Apical) Area

Located at the 5th intercostal space, left midclavicular line (apex); best for hearing S1 (loudest here), mitral regurgitation, S3, and S4.

Clinical Tip for Aortic Valve

Loudest A2 component of S2 is heard at the aortic valve area.

Clinical Tip for Pulmonic Valve

Best area to hear physiologic split S2.

Clinical Tip for Tricuspid Valve

Right-sided murmurs increase with inspiration.

Clinical Tip for Mitral Valve

Use the bell for low-pitched sounds like S3, S4, and mitral stenosis.

Stethoscope Diaphragm Usage

Use for S1, S2, most murmurs, and high-pitched sounds.

Stethoscope Bell Usage

Use for S3, S4, mitral stenosis, and low-pitched sounds.

Memory Trick for Auscultation Areas

All People Try Medicine (Aortic, Pulmonic, Tricuspid, Mitral); follow a Z-pattern down the chest.
