This paper reports on clinical evaluation of a wavelet denoising algorithm applied to ECG signal. The denoising method first the signal into the wavelet domain, then processes non-linearly the coefficients, and reconstructs the signal back to the tie domain. The described evaluation procedure of the denoising method was designed to test the clinical methodology that relies on cardiologist diagnoses. The preliminary results of the test, performed on a small ECG data set, are presented and discussed.
