Modelling and analysis of spherical models of cardiac electrical activity

The ability to relate data collected on the body surface to the electrical activity on the epicardial surface is of great importance in noninvasive detection and localization of many diseases of the heart. The computation of the potential distribution on the body surface from the potential distribution on the surface of the hearty (epicardial potentials) constitutes the forward problem in electrocardiography. Conversely, the problem of the reconstruction of epicardial potentials from body surface potentials is called the inverse problem in electrocardiography. Modeling and analysis related to these two problems are presented
