Figure 2

Simulation results of the heterogeneous 2D model locating in a 256 × 256 cell space. Different colors stand for different values of the dynamically computed membrane potential of cells. 36675 and 36606 are running steps; each step corresponds to 0.01 ms (mini second). The color strips between the inner surface and the outer surface show the normal endocardium-to-epicardium repolarization. At 366 ms most cells have undergone depolarization and are at the end of repolarization, the high accordance between picture A and picture B therefore indicates the validity and safety of the adaptive time step method. A. The distribution of membrane potential of cells in epicardium-to-endocardium repolarization without the adaptive time step. B. The distribution of membrane potential of cells with the adaptive time step. Pictures are captured with GIMP, a screen capture tool under Linux.
