You assess a 72-year-old male patient who comes into your clinic complaining of chest tightness and dyspnea, usually precipitated by exertion. Upon physical examination, you hear a murmur immediately after the 2nd heart sound when the patient is in a left lateral position. You conclude that what you hear is the third heart sound, and that it occurs during which part of the cardiac cycle?
