Techniques for processing vector electrocardiograms on a digital computer are described. The processed electrocardiograms frequently allow a more accurate diagnosis by the physician and a more accurate classification when the classification is done a

The first part of this paper is a description of the design of low-pass, bandpass, high-pass, and notched filter difference equations using Z-transform techniques. The difference equation coefficient word lengths are significantly reduced by using a

The spatial distribution of the QRS complex of 154 normal individuals was analyzed in this investigation. The three scalar vector components X, Y, and Z were recorded simultaneously at high speed on film, and the Lissajous loops of the three body pla

High-speed, simultaneous film recording of the scalar components X, Y, and Z is used for plotting vector loops with accurate spatial and temporal representation. Such loops are used for computing spatial magnitude and tilt position curves which are a

Two tables, representing simple circular functions with two variables are introduced which enable us to translate the Cartesian coordinates x, y, and z, given in plane projections, directly into spherical coordinates without numerical computation. Th
