Patent ID: 8684943

Claim:
A method of classifying a cardiovascular sound recorded from a living subject, said method comprises the steps of: identifying diastolic and/or systolic segments of said cardiovascular sound; dividing at least one of said identified diastolic and/or systolic segments into a number of sub-segments comprising at least a first sub-segment and at least a second sub-segment; identifying noisy sub-segments; discarding said noisy sub-segments; extracting from said first sub-segment at least a first signal parameter characterizing a first property of said cardiovascular sound, extracting from said second sub-segment at least a second signal parameter characterizing a second property of said cardiovascular sound, wherein said first and second sub-segments from which said at least first and second signal parameters are respectively extracted are from the same diastolic or systolic segment; and classifying said cardiovascular sound using said at least first signal parameter and said at least second signal parameter using a multiparametric discriminate function.
