| 摘 要： | 心电信号在采集、转换以及传输的过程中,因为受到设备、环境以及人体因素的影响,所采集到的心电信号常常伴有干扰,其中50 Hz工频干扰是影响心电信号识别的一个重要因素。在Levkov滤波的基础上,结合基于小波变换的QRS检测函数,对心电信号中工频干扰进行滤除。经过实验,该算法行之有效并且取得了较好的滤波效果。

| Abstract: | In the process of collection,transfer and transmission of ECG signal,because of the influence of the equipment,environment and human factors,the acquisition of ECG signal is often accompanied by interference,among which,50Hz power frequency interference is an important factor of affecting the recognition about the ECG signal.On the basis of the Levkov filter and QRS detection function based on the wavelet transform,this paper uses them to filter power frequency interference of ECG signal.Through the experiment,this algorithm is effective and it has achieved good filtering effect. |
