Abstract: A method and device for heart murmur extraction and classification is disclosed. Data corresponding to a heart sound/signal is acquired from a patient through a data acquirer. The heart sound data is processed to isolate systole and diastole periods. Features to discriminate between the defects types associated with different heart murmurs are extracted, and the heart murmurs are detected and identified based on the extracted features using a fuzzy controller.
