dc.description.abstractThis paper is concerned with the identification of splitting patterns in the second heart sound (S2) of the phonocardiogram signal (PCGs). The second heart sound S2 consists of two acoustic components A2 and P2 , the former is due to the closure of the aortic valve and the latter is due to the closure of the pulmonary valve. The aortic valve usually closes before the pulmonary valve, introducing a time delay known as “split”. A technique based on the discrete wavelet transform (DWT) and the continuous wavelet transform (CWT) is developed in this paper to measure the split To quantify the splitting, the two components in S2 (i.e. A2 and P2) are identified and, the delay between the two components can be estimated.en_US
