A New Quantitative Basis for Electrocardiographic Theory: The Normal QRS Complex

Abstract

A theory of electrocardiography based on a fixed-location, eccentric-dipole representation of ventricular depolarization and a homogeneous, resistive, linear medium in the shape of the human torso yields quantitative predictions of instantaneous amplitude and shape of QRS body surface potentials on one normal human subject to an accuracy of approximately ±15 per cent for electrodes dispersed over the entire torso.
