Ventricular fibrillation is a serious heart condition where the heart's lower chambers, or ventricles, quiver instead of pumping blood effectively. This chaotic electrical activity prevents the heart from maintaining a normal rhythm, leading to a lack of blood flow to vital organs, including the brain. If not treated immediately, ventricular fibrillation can result in cardiac arrest and death within minutes. Emergency treatment often involves defibrillation, a procedure that delivers an electric shock to the heart to restore a normal rhythm. Quick response is crucial for survival and minimizing potential damage to the body.
