We have developed a new approach to perform body surface Laplacian imaging of cardiac electrical activity by estimating the body surface Laplacian electrocardiograms from potential electrocardiographic signals. This paper describes a numerical algorithm to estimate the Laplacian electrocardiogram from the potential electrocardiograms. Computer simulation studies have been conducted to evaluate the accuracy of the developed approach in aspherical torso volume conductor and in a realistic geometry torso volume conductor. Our preliminary simulation results demonstrate the feasibility of performing body surface Laplacian imaging of cardiac electrical activity from body surface potential electrocardiograms.
