Abstract

This study is aimed to compare the spectral characteristics of bileaflet mechanical heart valve (MHV) sound signals produced by two different companies. For this, heart sound and ECG signals of patients whose aortic or mitral heart valves replaced using commonly used St. Jude and Sorin bileaflet MHV were recorded. Three features relating to frequency of heart sounds and three features relating to energy of heart sounds were obtained from power spectrum of the recorded heart sound signals. Then the features from same recording area and same heart valve were statically compared.
