Myocarditis is an inflammation of the muscle of the heart, causing it to function poorly. The inflammation is usually caused by a viral infection. Sometimes the patient recovers from the virus, but a process of inflammation started by the virus continues. Myocarditis is mostly seen in young infants. Some infants are exposed to a virus before being born. Treatment for myocarditis is based on treating the symptoms of the heart function. If mild or moderate, medications can help.
