In reality, the doctor trying to revive Annie is defibrillating a patient who is flat line (no electrical activity in the heart). This leads to the misperception that defibrillation 'jump starts' a heart. Nothing could be further from the truth. Defibrillation attempts to convert a chaotic rhythm (ventricular tachycardia or ventricular fibrillation) into a coherent rhythm. You don't shock flat line.
