摘要：

A means of analyzing acoustic heart sounds is described. The system analyzes heart sound data, isolating key features of the heartbeat signatures to produce a list of possible diagnoses. The system has six major components: heart bent extraction, segmentation of the heart sound circle, extraction of murmur data, time-frequency analysis of murmurs, statistical metrics and diagnoses algorithms. implementation of each component is discussed in detail. Diagnoses algorithms for the following events/conditions are included: heart rate, sinus arrhythmia, tachycardia, bradycardia, aortic stenosis and mitral regurgitation.
