Question

Quizplus · Accepted Answer

Ventricular fibrillation is the most dangerous type of arrhythmia as it can quickly cause cardiac arrest and death. It occurs when the heart's ventricles quiver instead of pumping blood effectively, leading to a lack of blood flow and oxygen to vital organs. Tachycardia and brachycardia can also be serious, but typically not as immediately life-threatening as ventricular fibrillation. Atrial fibrillation is a common type of arrhythmia but usually not as dangerous as ventricular fibrillation. An electrocardiogram is a diagnostic tool used to detect and diagnose arrhythmias, but it is not a type of arrhythmia itself.
