%X Signal transmission in the form of propagating waves of electrical excitation is a fast type of communication and coordination between cells that is known in cardiac tissue as the action potential.In this article we used an efficient model of cardiac ventricular cell that is based on partial differential equations(PDE).After that a computational algorithm for action potential propagation was represented that according to this algorithm and proposed efficient model, We demonstrated action potential propagation in one-dimensional (1D) and two-dimensional (2D) space lattices using the central finite-difference method.In addition we investigated the effect of obstacles on the propagation of normal action potential using represented 2D excitable medium.Our results show that proposed efficient model, represented algorithm and excitable media are suitable for simulation of action potential propagation in cardiac tissue.
