International ClassA61B 005/02AbstractApparatus for assisting in the analysis of heart sounds monitors heart sounds, ECG, and respiratory data. Once digitized, this data is processed and analyzed to determine timing relationships between the three signals, frequency (or pitch) of sounds, and dependence or non-dependence of sounds on ECG and respiratory phase. The user of the apparatus inputs the place of detection and the maneuver being performed. Raw phonocardiogram data is displayed. The user inputs the number of beats and the frames per second to display. Fast Fourier transformed and signal averaged data are displayed, and phase sensitive and non-phase sensitive sounds are extracted. A lesion fitting algorithm suggests diagnoses and possible further maneuvers to perform. The data obtained is compared to a historical patient data.Other References
