Abstract:

The goal of this research is to create a dependable algorithm that checks the identification and categorisation of the first cardiac sound (S1) and the second cardiac sound (S2) of a phonocardiogram (PCG) signal in the presence of extracardiac sounds. The algorithm uses intrinsic time scale decomposition (ITD) integrated with Shannon energy (SE) to analyse cardiac sounds' existence and identification from the processed data. The algorithm's performance has been assessed with accuracy and computational time. This cardiac sound classification technique is used in medical diagnosis systems to investigate pathological heart states further. The proposed method can enhance the reliable identification of S1 and S2 cardiac sounds with the detection accuracy of 95.2% and 90.5% for S1 & S2, respectively.

Keywords:

First cardiac sound, Second cardiac sound, Phonocardiogram, Intrinsic time scale decomposition, Shannon energy.
