Ventricular Fibrillation

Definition

The ventricles are the large lower chambers of the heart. They are responsible for moving blood to the organs and tissues of the body. In ventricular fibrillation, the heart’s ventricles contract in a rapid and chaotic manner. As a result, little or no blood is pumped from the heart. Unless emergency medical help is provided immediately, ventricular fibrillation will lead to cardiovascular collapse and sudden death.
