SYSTEM AND METHOD FOR CLASSIFYING A HEART SOUND
First Claim
1. A method of classifying a pre-processed heart sound signal of a patient, the method being characterised in that the pre-processed patient heart sound signal is electronically compared to a plurality of similarly pre-processed heart sounds corresponding to each of a plurality of pathologies and a diagnosis made by determining whether the patient heart sound corresponds to the heart sounds of any one or more of the pathologies.

Abstract
A method and system for electronically classifying a pre-processed heart sound signal of a patient as functional (normal) or pathological is provided. The pre-processed patient heart sound signal is segmentised and features are extracted therefrom (104) to build up a feature vector which is representative of the heart sound signal. The feature vector is then fed to a diagnostic decision support network (105) comprising a plurality of artificial neural networks, each relating to a known heart pathology, which is in turn used to conduct the classification.
