complexity for murmur identification and classification. The first stage of the classifier verifies
if the heart sound (HS) exhibits murmurs. To this end, the chaotic nature of the signal is
assessed using the Lyapunov exponents (LEs). The second stage of the method is devoted
to the classification of the type of murmur. In opposition to current state of the art methods for
murmur classification, a reduced set of features is proposed. This set includes both well …
