1. An external defibrillator comprising:
- a pair of flexible electrodes configured to be adhesively secured to the skin of a patient, each electrode including an electrically conductive layer comprising a metal that polarizes during a defibrillating pulse; and
a control unit configured to deliver a defibrillating pulse to the patient through the electrodes, the defibrillating pulse comprising a waveform configured to substantially depolarize the metal.

Abstract
An external defibrillator is provided including (a) a pair of disposable electrodes configured to be adhered to the skin of a patient, each electrode including an electrically conductive layer comprising a metal that is polarized during a defibrillating pulse, and (b) a control unit configured to deliver a defibrillating pulse to the patient through the electrodes. The waveform is configured to substantially depolarize the metal, and may be, for example, a biphasic waveform. Method of defibrillation and defibrillation electrodes are also provided.
