I40.1: Isolated myocarditis
The heart is composed of a thick muscle layer and a thin membrane inside the heart. An external sac, the pericardium, surrounds the heart. This sac consists of a protective membrane.
Your heart muscle is inflamed. When a heart muscle is inflamed, the heart may have an irregular beat or it may no longer pump enough blood through the body. This may result in missed heartbeats, chest pain, or shortness of breath, for example.
