Quizplus · Accepted Answer

Auscultation of the mitral and tricuspid areas is performed for low-pitched sounds,specifically an S₃ (otherwise known as a ventricular diastolic gallop or extra heart sound).Because S₃ is a low-pitched sound,it is best heard with the bell.An S₃ is an early diastolic filling sound that originates in the ventricles and is thus heard best at the apex of the heart.An S₃ originating from the right ventricle is best heard by placing the bell over the third or fourth ICS at the left sternal border.An S₃ originating from the left ventricle is best heard by placing the bell over the fifth ICS at the midclavicular line.
