If a Heart Murmur Were Discovered During the First Heart

Question

Examlex · Accepted Answer

The Answer is If a heart murmur were discovered during the first heart sound, the defective heart valve may be the mitral valve. The first heart sound, also known as S1, is produced by the closure of the mitral and tricuspid valves. If a murmur is heard during this sound, it may indicate a problem with the mitral valve, such as mitral valve regurgitation or stenosis. Mitral valve regurgitation occurs when the valve does not close properly, allowing blood to leak back into the left atrium during ventricular contraction. Mitral valve stenosis, on the other hand, occurs when the valve becomes narrowed, obstructing blood flow from the left atrium to the left ventricle. Both of these conditions can cause a murmur to be heard during the first heart sound.
