摘　　要：平滑滤波的目的是消除高频纹波干扰,ECG波形调理往往需要进行平滑滤波.平滑滤波会对高频尖峰波形产生削峰,ECG中的R波波形高尖,易受影响.讨论并实验了平滑滤波对不同采样率、心率和不同QRS间期时的R波削峰程度,进行了理论分析,给出了实验结果,为ECG的信号调理提供参考.By using smoothing filter, the high frequency noise in signal can be reduced. But it also makes the R - peaks distorting, and then affecting its amplitude. In this work, the tolerance of R - peak in different situation, such as different sampling and different interval of QRS wave, after smoothing filtering was analyzed and discussed. The theory analysis and experiment results were provided. It will be useful for ECG signal processing.
