Quantitative results of a critical experiment designed to determine influence of human-body inhomogeneity and applicability of fixed-location dipole hypothesis for ventricular depolarization are presented. Results reflect in pictorial form, conclusions that the fixed-location dipole representation is approximately 95 per cent accurate for the QRS complex at any body-surface point; influence of inhomogeneities on surface potentials is roughly ±10 per cent.
