Abstract

ECG is a method of measuring, displaying and recording the electrical activity of heart. In this paper, wavelet de-noising method has been examined to eliminate noise from the ECG signal. Using soft and hard thresholding process, the significant wavelet coefficients from each level are selected and denoised. ECG signal is reconstructed with inverse wavelet transform. Different thresholding algorithms are analyzed and their performances have been evaluated in terms of SNR. The standard MITBIH arrhythmia data from Physionet is used for the purpose.
