Defibrillation
From Simple English Wikipedia, the free encyclopedia
Defibrillation is the act of defibrillating the heart to try treat ventricular fibrillation or pulseless ventricular tachycardia. Defibrillation works by delivering a controlled electric current to the heart, which depolarises a critical mass of the heart muscle, which stops the arrhythmia and allows a coordinated heart rhythm to return. Defibrillation may be administered outside the body with the use of an external defibrillator or an automated external defibrillator, or inside the body with an implantable cardioverter-defibrillator.
