This paper addresses sharp, non-regular distortions appearing in ECG signal after applying wavelet denoising. Introduced distortions cause loss of the signal smoothness, that in the case of ECG signal are unacceptable. Source of such distortions was investigated and explained. Results of signal denoising process that is based on two wavelets, chosen from one family, are described and compared.
