A biodomain model for simulating propagation in multicellular cardiac tissue

The governing equations for evaluating propagation in a cylindrical bidomain are presented. The tissue model assumes equal anisotropy ratios. The simulations indicate that unlike the behavior noted in conventional one-dimensional models, the shape of the transmembrane potential, V_m, is affected by the conductivities. For mathematical simplicity, equal anisotropy is assumed, i.e., the ratio of the intracellular and interstitial conductivities is the same in the radial and axial directions
