Abstract
At least one swing value is determined responsive to a difference between maximum and minimum amplitude values of an auscultatory sound signal within a temporal region of a heart-cycle segment spanning an entire heart cycle of an auscultatory sound signal, wherein a location of at least one temporal region is responsive to a duration of the heart-cycle segment. Ssound presence is detected responsive to a ratio of Sto Sin relation an associated median value thereof from a population of test-subjects. A Support Vector Machine trained responsive to age, sex, Spresence and a plurality of heart sound swing measures provides for detecting CAD. Unsupervised classification of an Sswing and median and mean values of a Short Time Fourier Transform within associated frequency intervals, based upon data from a plurality of heart cycles of a plurality of test-subject provides for detecting presence of an Ssound.
