The treatment of choice in diagnosed ventricular fibrillation is
Defibrillation.The delivery of an electrical shock through the chest wall to the hea momentarily stops the hea and the chaotic rhythm. This often allows the normal hea rhythm to resume. If a public-use automated external defibrillator (AED) is available, anyone can administer it. Most public-use AEDs voice instructions as you use them. Public-use AEDs are programmed to recognize ventricular fibrillation and send a shock only when needed.
