Unsynchronized Cardioversion (Defibrillation)
Unsynchronized cardioversion or defibrillation is the delivery of a high-energy shock as soon as the button is pushed on defibrillator. This means it can be delivered anywhere in the cardiac cycle. By contrast, synchronized cardioversion (see Chap. 29) delivers a low-energy shock at the peak of the R wave in the cardiac (QRS) cycle.
