Immediate defibrillation is indicated for ventricular fibrillation because it is a life-threatening arrhythmia characterized by rapid, chaotic electrical activity in the heart that prevents effective pumping. The primary goal in treating ventricular fibrillation is to restore a normal heart rhythm as quickly as possible. Defibrillation involves delivering an electrical shock to the heart, which can reset the electrical activity and allow the heart’s normal rhythm to resume.

This intervention is crucial because, in cases of ventricular fibrillation, blood is not being effectively pumped to the lungs and rest of the body, leading to rapid deterioration of the patient’s condition. Prompt defibrillation is essential for survival and is considered the first-line treatment in advanced cardiac life support (ACLS) protocols for managing this arrhythmia.
