Video - Ventricular fibrillation
00:00 / 00:00
Video Summary
Ventricular fibrillation, also called v-fib or just VF, is when there's quivering of ventricular muscle fibers because they're not contracting at the same time. This results in failure to pump oxygenated blood to the brain, which within minutes can lead to sudden cardiac death. Prompt defibrillation and advanced cardiac life support measures need to be initiated to restore normal heart rhythm and prevent mortality.
