Abstract

In this paper we studied the influence of noise when extracting QRS from electrocardiographic (ECG) signal by means of Wavelet Multiresolution Analysis. Thus, we have made a time detection of QRS waves and heart rate both on a electrocardiography signal (ECG) and on the same electrocardiography signal over that overlapped different types of noises (white noise, 50 Hz noise, Gaussian noise and their combinations).
