What is the Difference between a Pacemaker and a Defibrillator?
... There are several reasons a defibrillator may be needed. The first reason would be a cardiac arrest that was caused by a ventricular arrhythmia. The next reason would be in someone that had a sustained ventricular arrhythmia that was documented but did not cause a cardiac arrest. These two sets of ...
