In this paper a filtering method for ECG signal is introduced which decomposes original ECG signals 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.
