The Research of Heart Sound Signal Energy Detection System
Aimed to enhance the efficiency of heart sound signal energy detection, a kind of heart sound signal energy detection system based on LabVIEW 8.5 is developed in this paper. The system makes use of saddlebag of signal processing and analysis tool of LabVIEW to detect and analyze energy of the heart sound signal. The system can detect, display, record and analyze the energy of heart sound signal. From the results of experiments, the detection and analysis of heart sound signal energy have importance clinical value to the earlier period diagnosis of coronary artery disease (CAD).
