DIGITAL FILTERING WITH APPLICATIONS TO ELECTROCARDIOGRAM PROCESSING.

Abstract

The first part of this paper is a description of the design of lowpass, bandpass, highpass, and notched filter difference equations using Z-transform techniques. The difference equation coefficient word lengths are significantly reduced by using a set of second-order difference equations. These equations have a form that minimizes computation. The second part of the paper contains applications of these filters to the processing of electrocardiograms (ECG). The filters are included as subroutines in a program that also includes an adaptive muscle tremor filter, an 'optimum' ECG estimator, and optimum estimators for the arrival time of various parts of the ECG waveform. Clinical results are presented. (Author)
