Electrocardiogram baseline wander removal using stationary wavelet approximations
Beatrice Arvinti, Dumitru Toader, Marius Costache, Alexandru Isar · 2010
In this paper, a method to reduce the baseline wandering of an electrocardiogram signal is presented. The described method is based on stationary wavelet approximation of the whole signal. The main advantage of this method, compared with others, is the fact that it is a non-supervised method, allowing the process to be used in an automatic analysis of electrocardiograms. Moreover, the results are as accurate as those obtained with other methods of baseline wandering removal, methods considered as references in the scientific bibliography.
