A defibrillator identifies abnormal heart rhythms, specifically life-threatening arrhythmias such as ventricular fibrillation and pulseless ventricular tachycardia. It monitors the heart's electrical activity and determines whether a shock is needed to restore a normal rhythm. If a shock is warranted, the device delivers an electric shock to the heart to help reestablish a coordinated heartbeat.
