title: Digital computer analysis of the QRS complex of the dog, using the McFee axial system.
abstract: Digital computer analysis of the canine orthogonal electrocardiogram was performed on 30 clinically normal dogs, as recorded by the McFee axial system. The spatiogeometric properties calculated included: time duration of QRS, time integral of QRS, eigenvalues of the QRSsE loop, eigenvectors, spatial magnitude, and spatial velocity. Electrocardiograms were recorded by FM tape recorder, analogue-to-digital conversion performed, and the analytical procedure utilized the IBM 360/75 digital computer controlled by a FORTRAN G source program. The QRS complex and spatial values were qualitatively similar to those in other reports.
