Adaptive noise cancellation in ECG signal

Control over the state of the cardiovascular system is found in cardiac monitoring devices, namely in electrocardiography. When registering electrocardiograms with the help of electrodes located on the patients torso, the impact of electrical and physiological disturbances is unavoidable. In this article presents a new approach of adaptive processing of ECG signals, to eliminate electrical and physiological disturbances. Synthesis of adaptive sequential filters is performed at the request of the American Heart Association. The proposed approach is based on adaptive sequential filtering of ECG signals in the time domain. With this filtration, the accuracy characteristics of the measured electrocardiographic information are increased and the noise robust identification of local sections ECG signal is obtained.
