Technology Description

An integrated system to acquire and process digitized heart sound signal for identification of valvular heart diseases with training, self-test, report generation and display facilities. The invention is an integrated system to acquire and process digitized heart sound signal for identification of valvular heart diseases with training, self-test, report generation and appropriate display facilities. In auto mode, decision making is performed for normal and nine common pathological cases in four different stages: acquisition of heart sound, segmentation of primary heart sounds, feature extraction and classification of heart valve disorders with a certain confidence score developed from disease model. In manual mode, the first two stage described above is followed by display of one heart sound cycle, frequency spectrum and spectrogram (time-frequency information).

The claimed invention consists of four subsystems:

(i) Data acquisition
(ii) Data compression and decompression
(iii) Recording and display
(iv) Decision-making. It can be used as training device, too.
