When are AEDs beneficial?

AEDs automatically check the victim's heart rhythm and determines if a shock may correct it.  Defibrillation is particularly successful on a rhythm known as ventricular fibrillation, or v-fib.  V-fib means that the ventricles of the heart are beating very fast, or quivering.  The AED may help return the heart to a normal rhythm.  The faster that an AED is used on a victim, the greater the chance of survival.
