This work is concerned with the development of numerically efficient approaches to integrated cardiac electrophysiology within the bidomain setting. While the excitation of cardiac tissue involves two field variables, namely the transmembrane potential and the extracellular potential, the electric activity of the torso involves the extracellular field only. Two partial differential equations define the electrophysiological behavior of the heart, and one of these equations contains a highly non-linear current term that is modeled by the ten Tusscher model. The linear and time-independent nature of the differential equations describing the electrical behavior of torso enables us to propose computationally efficient approaches. The coupling of the boundary element and the finite element methods on the heart surface yields efficient numerical results in terms of computational time. Moreover, the physiological results of the proposed model are tested for a healthy case where favorable results are obtained
