Internal cardioversion. Internal cardioversion for atrial fibrillation is used in patients who are resistant to external cardioversion or inadvertently induced during an electrophysiologic study. Cardioversion should occur before placement of an atrial defibrillator.
Cardioversion is a procedure that uses external electric shocks to restore a normal heart rhythm. Overview Cardioversion is called defibrillation when it is done in an emergency to prevent death due to potentially fatal ventricular arrhythmias that can result in sudden cardiac arrest. Alternatively, your doctor can schedule cardioversion as a way to treat arrhythmias in the upper chambers of your heart called atrial fibrillation.
