Variability of Pulmonary Blood Pressure, Splitting of the Second Heart Sound and Heart Rate

L Hamza Cherif and SM Debba

The study of variation and the change of the second heart sound split (a change related to the inspiration and the expiration) can determine at what time in a cardiac cycle is the inspiration and the expiration. The heart rate increases during the inspiration and decreases during the expiration. It would also be interesting to study the variation in systolic pulmonary artery pressure (SPAP) estimated over several cardiac cycles and understand its evolution since its variation is related to the pulmonary valve on the one hand and the inspiration and the expiration of another part. The algorithm developed based on the Hilbert transform and the energy of Shannon give the second heart sound split. The SPAP will be estimated from the spectral parameters of the second heart S2.
