Abstract:
1. A system for analyzing a heart having a first cardiac valve and a second cardiac valve, the system comprising: a heart sound input to receive one or more signals each indicative of heart sounds; a heart sound detector, coupled to the heart sound input, to detect heart sounds of at least one predetermined type from the one or more signals; and a computer-based heart sound morphology analyzer, coupled to the heart sound detector, to produce at least one dyssynchrony parameter indicative of a degree of cardiac mechanical dyssynchrony, the heart sound morphology analyzer including a heart sound measurement module to measure one or more parameters each based on at least one morphological feature of the heart sounds of the at least one predetermined type, the at least one morphological feature indicative of a time interval between closures of the first cardiac valve and the second cardiac valve in one cardiac cycle.
