Abstract
The anisotropic conductivity of cardiac tissue and features of the anatomical architecture of the heart, such as the transmural rotation of fibers from the epicardium to the endocardium or their spiral rotation near the apex [1, 2], have a profound influence on the heart’s propagated excitation and the generation of extracardiac electric potential and magnetic field—as has been substantiated by many experimental findings (e.g.[3, 4]). Therefore it is of great interest to study the propagation phenomena and the associated electromagnetic field in mathematical models that represent realistically the anisotropic heart. We have addressed this problem, and the result of our efforts is a model [5, 6, 7] whose salient features related to the propagation algorithm are highlighted in this paper; a companion paper [8] deals with features related to extracardiac electric and magnetic fields.
