The image show an example of a "Temporal View". Simulation start at time t=0 and end at time t=100ms. Each single image show potential distribution in the slices from 16 to 29. Heart leans to the left side of the body; so ventricles are visible at the left side of the image and atria at the right side. In this simulation ventricles are characterized by a slow depolarization of nodes and by a fast propagation of signal within ventricular tissues. Atria are characterized by a quick depolarization of nodes and by a slow propagation of signal within atrial tissues.
