Abstract

The removal of artifacts from the ECG signals is essential for further diagnostic analysis. Wavelet transform has become a promising tool for the multiscale representation and analysis of signals. The key steps of signal denoising based on wavelet packet transform are the selection of the threshold and shrinkage function. In non-stationary signals such as ECG, the wavelet transform provides more computational complexity. In this study, we developed an ECG denoising method based on wavelet packet transform. The MATLAB software was used to analyze the ECG signal. In this study, different wavelets were used in different EGC signals for many patients and compared to find suitable wavelets.
