Abstract
A method and apparatus for examining the QRS complex of ECG signals to detect minute late potentials. The system functions to filter the QRS signals bi-directionally, and further separately processes the two filtered signals through selected window functions before summation. The summed signal is then passed through a smoothing function to produce an output signal of ideal phase that delineates any late potentials within the QRS complex.
