Question

Quizplus · Accepted Answer

Ventricular fibrillation is the most life-threatening form of arrhythmia because it can quickly lead to loss of consciousness, cardiac arrest, and death if not treated immediately. It occurs when the heart's lower chambers quiver instead of contracting properly, which prevents the heart from pumping blood effectively. Atrial fibrillation, tachycardia, and bradycardia are also serious arrhythmias but are generally not as immediately life-threatening as ventricular fibrillation.
