A new adaptive scheme for ECG enhancement

Abstract ECG recordings during effort tests present different kinds of interferences. Several noise cancelling methods have been presented in literature, and, among them, adaptive ones have shown a good performance. In this paper, a new scheme for adaptive filtering of ECG signals is presented. It is based on two previously published algorithms which perform inter-beat average. Hence, their outputs are not always suitable. Our modifications provide a better output ECG signal since it is not an inter-beat average. Moreover, this scheme is simpler from a hardware point of view, as only one recording channel is required.
