So far, fractal complexity is used for heart rate variability [ 13 , 14 ], as well as for the auscultatory recording classification [ 15 ], where FD is shown as a satisfying tool in comparison to the other time-frequency features. Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart.
