Abstract :
A bidomain model of the myocardium has been successfully used in predicting the tissue response to a strong shock. The studies of active tissue behavior have been limited due the computational expense of solving bidomain equations. The goal of the present research is to develop a reasonable approximation to the bidomain that would require a fraction of computer time necessary for full bidomain simulation. This reduced bidomain model preserves such important characteristics of the full bidomain as the shape of virtual electrodes, the rate at which they develop, and the effect they have on existing fibrillation wavefronts
