Medical Term:

systolic click


a sharp, clicking sound heard during cardiac systole; when heard in early systole it is usually an ejection sound; in late systole the click usually signifies mitral insufficiency, as in the dysfunction of the mitral valvular apparatus when it prolapses into the left atrium during systole (see Barlow syndrome); rarely may also be due to pleuropericardial adhesions or other extracardiac mechanisms.
