摘要

This paper reports a simple and efficient method to detect the QRS-segment in ECG signals. The method suggested by the authors is implemented in two steps. The Step I forms the detection of R-peaks which is accomplished after three main operations : band pass filtering, 3-sample area estimation and M-sample window averaging with thresholding. While the band pass filtering suppresses the noise, the 3-sample area estimation enhances the the signal to noise ratio (SNR) and hence the detectability of R-peaks. Finally, M-sample window averaging smoothens the R-peak envelopes. The thresholding pinpoints the R-peaks. After R-peaks are detected their location is confirmed in Step II which also marks the location of Q and S points resulting in determination of respective QRS-segments.
