A simulation study has been conducted to evaluate the performance of body surface Laplacian maps (BSLMs) in localizing and imaging ventricular myocardial infarctions. A two-site myocardial infarction simulation protocol was used to simulate infarcts on the anterior, lateral and posterior epicardium, as well as anterior endocardium. A realistically shaped torso model and a finite element model of ventricles were used in the present simulation study. The present simulation results suggest that the BSLM has enhanced performance in localizing and imaging multiple myocardial infarctions. This enhanced capability of the BSLM may lead to important applications in assisting clinical diagnosis and management of cardiac infarctions. Copyright (C) 1998 Elsevier Science S.A.
