Abstract:
In this paper,two-channel difference method was introduced to extract R-peak of ECG.In this method,one channel was used to deal with the source ECG,the other was used for the smoothed ECGsignal.By comparing,emending of difference method,the source R-peak of ECGcould extract exactly from the co-channel.Experiments showed the method had following advantages,such as a high-extracting rate,stronger anti-interference,high stability,high Robust,and easy realization.This method could also be used to extract the Qand Speaks.
