Three-dimensional simulation of epicardial potentials using a microcomputer-based heart-torso model

摘要: Previous cardiac simulation studies have focused on simulating the activation isochrones and subsequently body surface potentials. Epicardial potentials, which are important for clinical applications as well electrocardiography inverse problem studies, however, usually been neglected. This paper presents a procedure of epicardial potentials using microcomputer-based heart-torso model with real geometry. The heart developed earlier was composed more than 60,000 cell units used in this study. To simulate an enclosed whole constructed. model, together mounted inhomogeneous human torso model. Electric dipoles, proportional to spatial gradient action potential, generated all units. These dipoles give rise potential distribution surface, is calculated by means boundary element method. simulated maps during normal beat patients left bundle branch block (LBBB) close agreement those reported literature.
