Defibrillation is indicated to treat which arrhythmia?

Explanation:
Defibrillation targets shockable rhythms where the heart isn’t effectively pumping. The classic shockable rhythms are pulseless ventricular tachycardia and ventricular fibrillation. It is not used for rhythms with a pulse, such as supraventricular tachycardia, nor for non-shockable rhythms like asystole. Among the options, pulseless ventricular tachycardia is the rhythm that is treated with defibrillation because it is a rapid, life-threatening ventricular rhythm that benefits from an unsynchronized shock to reset the cardiac electrical activity. If ventricular tachycardia occurs with a pulse, a synchronized cardioversion (not defibrillation) would typically be used instead.
