Abstract: In order to further highlight heart sound signals analysis, we developed an algorithm to isolate each of sounds S1 or S2 to provide an assessment of their duration, the interval between their internal components and an estimation of their spectral parameters for estimation of pulmonary artery systolic pressure, for possible discrimination depending on the severity of pathological cases for different heart sound signals.
