Why is rapid defibrilation important to survival?

Rapid defibrillation is crucial for survival during cardiac arrest because it restores normal heart rhythm by delivering an electric shock to the heart. The sooner defibrillation occurs—ideally within a few minutes of the cardiac event—the higher the chance of survival and minimizing brain damage. Delayed defibrillation significantly decreases the likelihood of successful resuscitation, as the heart remains in a chaotic rhythm that prevents effective blood circulation. Thus, timely access to defibrillation is a key factor in improving outcomes for cardiac arrest victims.
