Abstract
ECG is an important key to diagnose heart diseases. The diagnosis is affected by the quality of ECG, which might be influenced by several artifacts such as power line interference and baseline wander. In this paper, two efficient methods based on a combination of a wavelet transform with least mean square (LMS) and/or adaptive neuro-fuzzy inference system (ANFIS) is proposed to canceler interferences and baseline wander from contaminated ECG signal. Our experiments show promising results.
