What is the typical heart rate for ventricular fibrillation?

• A. 60-100 bpm
• B. Under 60 bpm
• C. Over 350 bpm
• D. 100-200 bpm

Answer: (C)

Ventricular fibrillation is characterized by chaotic and disorganized electrical activity in the ventricles, which leads to ineffective contraction of the heart. This condition results in the heart not pumping blood effectively, and instead of a measurable heart rate, the electrical activity can be so erratic that it is often considered to have an extremely high theoretical rate of over 350 beats per minute. However, this does not correspond to a functional heartbeat, as the heart is not able to maintain any coordinated rhythm, leading to the absence of a pulse. Understanding this, a heart rate classified as "over 350 bpm" reflects the rapid and disordered electrical activity typical of ventricular fibrillation, which is critical to know for responding to cardiac emergencies and initiating appropriate treatment such as cardiopulmonary resuscitation (CPR) or defibrillation.
