Which statement correctly differentiates cardioversion from defibrillation?
a. Defibrillation is a synchronized shock delivered to depolarize the mycocardium
simultaneously in atrial fibrillation.

supraventricular tachycardia. - answerd. Cardioversion delivers a synchronized shock
for ventricular tachycardia or supraventricular tachycardia.
