A patient learns he has a heart murmur. His physician hears abnormal sounds during the S1 heart sound. Determine a potential cause of his heart murmur

What will be an ideal response?


This patient probably has a heart murmur caused by a defective valve. Since his physician hears abnormal sounds during the timing for the S1 heart sound, his defective valve is either the tricuspid valve or the mitral (bicuspid) valve. The S1 sound, or "lub" is heard when the atrioventricular (AV) valves (tricuspid and mitral valves) close.
