Abstract :
One of the significant means for examining the left ventricle functions is to measure the heart systolic time intervals (STI) of ECG, PCG, and CPT signals. The digital signal processing techniques for these three physiological signals and algorithms for detecting and recognizing their characteristic points and processing a variety of interferences are discussed. The recognition of the characteristic points in the CPT was found to be related to the first and the second heart sounds. This method requires much less computation and is implementable with microcomputer systems.<>
