Abstract

An improvement of the electrocardiographic body surface potential mapping technique is proposed to provide more explicit recognition of excitation processes in the heart by means of calculation of the potential distribution on the spherical quasiepicardium and separation of its extremum regions. The method is illustrated with cases of ventricular extrasystole and preexcitation syndrome
