When the heart is defibrillated, a controlled electric shock is delivered to restore normal rhythm in cases of life-threatening arrhythmias, such as ventricular fibrillation or pulseless ventricular tachycardia. This shock depolarizes the heart muscle cells, temporarily stopping all electrical activity, which allows the heart’s natural pacemaker (the sinoatrial node) to regain control and re-establish a coordinated heartbeat. The goal is to reset the heart's electrical system and restore effective circulation.
