New method to disrupt spiral waves may be a less painful way to defibrillate hearts

A spiral wave of electrical activity in the heart can cause catastrophic consequences. One spiral wave creates tachycardia - a heart rate that's too fast - and multiple spirals cause a state of disorganized contraction known as fibrillation.
