What term describes the condition where the ventricles stop contracting properly and only quiver?

• A. Fibrillation
• B. Tachycardia
• C. Bradycardia
• D. Asystole

Answer: (A)

Ventricular fibrillation is when the ventricles lose coordinated electrical activity and simply quiver instead of contracting. This chaotic, ineffectual activity means no blood is being pumped to the rest of the body, which is life-threatening and requires immediate defibrillation and CPR to try to restore a usable heartbeat. Tachycardia describes a fast heart rate, usually with some rhythm still present; bradycardia is a slow heart rate; asystole is the absence of electrical activity (a flatline). Among these, only the quivering ventricles point to ventricular fibrillation.
