Heart block occurs when electrical signals from the upper chambers of the heart (atria) cannot travel to the lower chambers (ventricles). The ventricles then beat too slowly, decreasing the amount of oxygen that gets to the body and brain. This causes a slow pulse and can result in a lack of energy, feeling lightheaded or fainting.
