Final answer:
The goal of defibrillation is to reset the pacemakers in the SA node and establish a perfusing rhythm. It is a useful intervention in patients with prolonged asystole.
Step-by-step explanation:
The goal of defibrillation is to reset the pacemakers in the SA node and establish a perfusing rhythm. It is a useful intervention in patients with prolonged asystole. Defibrillation delivers a large shock of electrical energy to the heart to correct abnormal heart rhythm, such as cardiac or ventricular fibrillation, and allow the body's natural pacemaker to resume its normal rhythm.
