VF stands for?

• A. Ventricular Failure
• B. Atrial Fibrillation
• C. Ventricular Fibrillation
• D. Fibrillation Ventricular

Answer: (C)

VF stands for ventricular fibrillation. This is a life-threatening rhythm where the ventricles quiver and fail to contract in a coordinated way, so the heart can’t effectively pump blood. Immediate defibrillation and CPR are required because blood flow stops, leading to collapse if not treated quickly. The other terms aren’t correct here: atrial fibrillation is a different rhythm that originates in the atria and is typically denoted AFib, not VF; ventricular failure refers to heart failure (HF), not a fibrillation rhythm; and saying “fibrillation ventricular” isn’t the standard term or order used in medical naming.
