Fighting Waves With Waves

The electrophysiology of the heart really matches well with what we call in physics or in math, apply math. An excitable system has a lot of mathematics behind that can be used on nonlinear systems and chaotic systems. So one of the things that we can do is know when to perturb with small shocks instead of one big shock. It was very nice because we were able to defibrillate hearts with using just 10% of the energy. We've been successful so far.
