A Phonocardiogram (PCG) is a graphic record of heart sound is an important first step in evaluating the cardiovascular system. In this study, a phonocardiogram signal has been decomposed into S1, S2 and S4 waves and average power and dominant frequency has been computed from segmented bursts of these signals. A Bayes classifier has been used for categorizing normal and abnormal heart sounds. The results show that this simple approach is significant to determine some abnormalities in the heart rhythm.
