Defibrillators are devices that control a patient's heart rate by sending an electric pulse or shock to it. It's used to prevent dangerous disorders like ventricular fibrillation, cardiac arrhythmia, and pulseless ventricular tachycardia. Its major function is to deliver an electric shock to the heart, depolarizing the cardiac muscles and allowing the heart to restore normal electrical activity.
An implantable cardioverter defibrillator (ICD) is a piece of equipment or a device that is placed inside the body to perform cardioversion, pacing, andDefibrillatorsof the heart. Ventricular fibrillation, cardiac arrhythmias, and pulseless ventricular tachycardia are the most common causes of sudden cardiac arrest.
