Abstract :
A thin sheet of cardiac tissue is modeled as a set of resistively coupled excitable cables with membrane dynamics described by the modified Beeler-Reuter model. A fast, efficient calculation scheme is described for simulating a network of 50 cables. The results bring to light interesting differences between axial and transverse propagation. It is shown that the density and resistance of transverse connections are important determinants of the anisotropic velocity ratio
