Statistical Deconvolution of Electrocardiograms
Bruce A. Eisenstein, Louis R. Cerrato · IEEE Transactions on Biomedical Engineering · 1978
Distortion caused by the passage of an electrocardiogram (ECG) through a linear, time-invariant system can be removed by deconvolving the impulse response of the distorting system from the observation. By modeling the ECG as a cyclostationary signal, the deconvolution can be done without a priori knowledge of the impulse response of the distorting system.
