What is defibriation?

Defibrillation is a medical procedure that involves delivering a controlled electric shock to the heart to restore its normal rhythm during life-threatening arrhythmias, such as ventricular fibrillation or pulseless ventricular tachycardia. The shock aims to depolarize the heart muscle, allowing the natural pacemaker to regain control and re-establish a coordinated heartbeat. This procedure can be performed using an automated external defibrillator (AED) or a manual defibrillator by trained healthcare professionals. Timely defibrillation is critical for improving survival rates in cardiac arrest situations.
