摘　　要：介绍了应用样条函数插值的方法来提取运动心电信号中异常 QRS复合波内高频分量 ,并定义了残余信号的 QRSε作为衡量指标 ,取得较好的结果。This article introduces a method of extracting high frequency components of abnormal intra QRS of exercise ECG signal by using spline function interpolation algorithm, and defines QRS ε of the residual signal as quantitative index.Some expected results have been obtained. This method is an effective measuring approach to further researches on the high frequency components of exercise and other ECG signals.
