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。这个方法是进一步研究运动心电信号或其它心电信号中高频分量变化的有效检测手段
The method of spline interpolation is introduced to extract the high frequency components of abnormal QRS complex in ECG, and the QRSε of residual signal is defined as a measure to get good results. This method is to further study the movement of ECG or other ECG signals in the effective detection of high-frequency components
