The heart generates its own electrical supply in order to make the muscles in the heart contract. A change to a person’s normal heart rhythm can sometimes have a catastrophic effect. The most deadly of these rhythm disturbances is Ventricular Fibrillation (or, as you may have heard on tv shows, shortened to VF). The most successful treatment for VF is a shock from a defibrillator. When VF occurs, instead of the heart pumping blood around the body, it quivers like an imaginary sack of wriggling worms. It means that oxygenated blood is no longer being pumped around the body by the heart. As a result, the person collapses, the cessation of breathing and the heart muscle dying.
