Application of Filtering Methods for Removal of Resuscitation Artifacts from Human ECG Signals
Band-pass, Kalman, and adaptive filters are used for removal of resuscitation artifacts from human ECG signals. The paper is tutorial and clarifies the rationale for applying these methods in the particular biomedical context. Novel aspects of the exposition are deterministic interpretation and comparative study of the methods. A database of separately recorded human ECG and animal resuscitation artifact signals is used for evaluation of the methods. The considered performance criterion is the signal-to-noise ratio (SNR) improvement, defined as the ratio of the SNRs of the filtered signal and the given ECG signal y. The empirical results show that for low SNR of y a band-pass filter yields the best performance while for high SNR an adaptive filter yields the best performance.
