| 摘 要： | 在ECG特征点提取过程中,引入双通道信号处理的思路.其中一个通道为原ECG信号,另一辅助通道则对ECG信号进行调理至平滑后,通过运用差分和引入校正的方法,确定出原ECG信号通道中的R波峰点.实验结果表明,该方法可充分发挥经典差分法的优越性,在检测R峰点时具有识别率高、抗干扰力强、算法稳定性高及算法简单的特点,该方法可同时检出Q及S峰点. |

| 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. |
