Simulation of electrical impulse propagation through the heart during ventricular fibrillation. Colour represents the transmembrane potential--i.e. the voltage across the cell membrane--on the surface of the heart. Yellow indicates largest potential values while dark red represents resting level. This simulation was performed by Pras Pathmanathan and Richard A. Gray at the US Food and Drug Administration (FDA), using the software package Chaste, together with a high-resolution anatomically-detailed computational mesh of the rabbit ventricles, and was run on FDA's high performance computing resources in the Center for Devices and Radiological Health (CDRH).
