Question

Quizplus · Accepted Answer

A prolapsed mitral valve causes the valve to become floppy or loose, which leads to blood regurgitating back into the left atrium during contraction of the left ventricle, resulting in decreased forward flow of blood from the heart, and increased effort of the left ventricle to pump blood. This, in turn, can lead to symptoms like fatigue, palpitations, and shortness of breath. Therefore, the best choice is increased effort by the left ventricle and regurgitation (Option E).
