Question

Quizplus · Accepted Answer

Defibrillators deliver an electric shock to the heart to help it reset and begin functioning properly again. This electric shock is usually delivered to the heart's pacemaker, which can then start beating at a normal rate again. Defibrillators do not pump adrenaline or massage the heart using remote sensors, and while they can be used in conjunction with CPR, they do not automate the process. Therefore, the best choice is B - they deliver an electric shock to the heart's pacemaker.
