摘　　要：介绍用小波变换实现心电图（ECG）信号滤波处理的方法．该方法采用小波变换将原始心电信号分解为不同频段下的细节信号，去掉某些细节信号，再用小波逆变换恢复保留信号，就能实现心电信号中的三种主要的消除．从实验结果看，本方法行之有效．In this paper a filtering method for ECG signal is introduced which decomposes original ECG sig-nals into detail signals on different frequency bands by using Wavelet Transform(WT). According to ECG signal feature,some detail signals are discarded,and the retained signals are reconstructed by inverse WT,so three main interferences in ECG signal can be removed. Our experimental results demonstrate that this is an efficient filtering method.
