Causes of First Degree Heart Block. Many highly conditioned athletes with an increased vagal tone have a first degree heart block. Vagal tone is an intrinsic inhibition of heart beats by the vagal nerve that is responsible for slowing down the heart. Other causes of first degree heart block are: Infectious disease â such as Lyme disease, which is associated with carditis (a heart complication of the disease) and usually found in children; viruses can also cause myocarditis or inflammation of the heart muscles.
Acquired heart block is more common than congenital heart block. Damage to the heart muscle or its electrical system causes acquired heart block. Diseases, surgery, or medicines can cause this damage. The three types of heart block are first degree, second degree, and third degree. First degree is the least severe, and third degree is the most severe. This is true for both congenital and acquired heart block. Doctors use a test called an EKG (electrocardiogram) to help diagnose heart block.
