Myocarditis

Also known as: inflammation of the myocardium, inflammation of the heart

​What is Myocarditis?

The myocardium is the thick layer of muscle tissue in the center of the wall of the heart. When it becomes inflamed, the disorder is known as myocarditis which may lead to a number of symptoms.

What causes myocarditis?
Viruses are the most common cause of myocarditis, however  bacteria, parasites and fungi can also cause myocarditis. In rarer instances, certain medications or exposures to chemicals, radiation, or toxins can lead to myocarditis. Some diseases which cause inflammation throughout the body, for example rheumatoid arthritis, may also involve the heart and cause myocarditis.

What are the symptoms of myocarditis?
Some children may have very  few,  difficult to detect symptoms, however as myocarditis  affects the heart’s ability to pump blood normally, symptoms can include trouble breathing, heart palpitations, chest pain, fatigue and fainting.

What are myocarditis care options?
In many cases myocarditis can be treated with medications that help the heart pump blood more easily. Most children with good medical treatment will recover completely. When myocarditis is severe, surgery or the implantation of a pacemaker might be required to help the heart work more efficiently.

Free EKG Screenings

The Heart Program at Nicklaus Children’s Hospital provides electrocardiogram (EKG) screenings to children and young adults in the community at no cost. The focus of this program is to create awareness on the importance of pediatric heart screenings in an effort to identify children at risk of sudden cardiac arrest (SCA). The use of an electrocardiogram (EKG) is critical to help diagnose asymptomatic heart defects that  may not otherwise be detected in a routine physical. Learn more.
