1. An apparatus for averaging a plurality of electrocardiographic waveforms having P, Q, R, S, and T-segments to form ameans for sampling said plurality of electrocardiographic waveforms periodically and for generating a sequence of input data samples indicating the amplitude of the electrocardiographic waveforms at each sampled time;

  • means for selectively filtering a first frequency spectrum from said input data samples to produce first filtered data samples, said first frequency spectrum corresponding to the major signal frequency components of the QRS-segments of the waveforms;
