A unitary concept is proposed to explain the genesis of the third heart sound and associated "rapid filling wave" of the apexcardiogram in physiological and pathological states including constrictive pericarditis. This theory not only clarifies the hitherto unexplained phenomenon such as presence of S3 in significant mitral stenosis, but also places in

Abstract The second heart sound was studied in 80 patients with systolic or diastolic overload of the right ventricle. In patients who had moderate or severe pulmonary stenosis the second sound was wide and fixed during respiration; it was also wide and fixed in patients who had a considerable left-to-right shunt at the atrial or ventricular level ...

A personal experience is reported for the benefit of persons experimenting with audible repetitive sound pulses. Prolonged exposure to pulses having a repetition rate higher than the normal heart-beat rate appears to fix the cardiac rhythm at an abnormally high rate.
