Ventricular fibrillation (V-fib or VF) is a condition in which there is uncoordinated contraction of the cardiac muscle of the ventricles in the heart, making them quiver rather than contract properly. In this condition, ventricle muscles in the heart begin to contract in a disorganized fashion, making them quiver. Due to this uncoordinated contraction, blood circulation may cease within minutes, which may be fatal.
