Abstract

A uniform electric field of weak intensity was applied across the heart and was found to be sufficient to unpin the rotating waves. It was found that the effect rests on the response of cardiac tissue. It was shown that the physics of electric field distribution between cardiac cells permits one to deliver an electric pulse exactly to the core of a pinned wave. It was also found that the energy needed is two orders of magnitude less than the defibrillation energy.
