A paced beat, in 3D

The ventricles below are the Rodero average heart, cut open. A pacemaker stimulus is given at the apex of the right ventricle and the simulated wave spreads from cell to cell through the muscle. Drag the heart to turn it; move the cut to see the wave inside the wall. The strip underneath is computed from the same simulated field.

This is not how a normal heartbeat spreads: a normal beat reaches the muscle through the fast conduction system and finishes in under 120 ms.
