Abstract: The phonocardiogram (PCG) signal processing approach seems to be very revealing for the diagnosis of pathologies affecting the activity of the heart. The aim of this paper is the application of an algorithm to explore heart sounds with simplicity in order to provide statistical parameters to better understand the cardiac activity by the calculation of the cardiac frequency and examine the impact of minor and pronounced murmurs on the cardiac variability. This paper is conducted to clarify the variation of the cardiac frequency affected by several groups of murmurs and investigate the medical reasons behind the obtained results. A high number of cycles were used to better refine the expected results.
