There is still considerable variance of opinion, controversy and debate among investigators as to the exact causes of the heart sounds. This is especially true of the first heart sound. It is fairly well agreed among most investigators that the second heart sound is due chiefly to the closure of the semilunar valves. Most of the controversy has been and still is concerned with the cause of the first heart sound. In the past there have been as many as 40 theories proposed... This content is PDF only.
