Abstract: Heart sounds of patients are usually used for analysis by cardiologists for the purpose of early detection of various heart diseases. In this paper, Hilbert-Huang transform (HHT) is applied to analyse five different kinds of mechanical prosthetic heart valve sounds, and an HHT-based feature extraction procedure is also developed to classify these five different mechanical heart valve sounds.

Keywords: heart sounds; mechanical heart valves; prosthetic heart valves; Hilbert-Huang transform; HHT; heart sound classification; feature extraction.
