== Symptoms ==
* Chest pain that may resemble a heart attack
* Fatigue or listlessness
* Fever and other signs of infection
* Joint pain or swelling
* Leg swelling
* Pale, cool hands and feet
* Rapid breathing
* Rapid heart rate
* Fainting, often related to irregular heart rhythms
* Low urine output

== Work up ==
Myocarditis can be hard to diagnose because the signs and symptoms often mimic those of other heart and lung diseases, or a bad case of the flu.

'''Physical exam'''
There may be signs of infection, including fever and rashes.

'''Imaging studies'''
* A chest x-ray can show enlargement (swelling) of the heart.
* Electrocardiogram may also be done to help make the diagnosis.
* Heart biopsy is the most accurate way to confirm the diagnosis, but it is not always needed
* Other tests that may be needed include:
* Blood cultures to check for infection
* Blood tests to look for antibodies against viruses or the heart muscle itself
* Blood tests to check liver and kidney function
* Complete blood count
* Special tests to check for the presence of viruses in the blood (viral PCR)

== Treatment ==
* Treatment is aimed at the cause of the problem, and may involve:
* Antibiotics to fight bacterial infection
* Steroids to reduce swelling
* Intravenous immunoglobulin (IVIG)
* Diuretics to remove excess water from the body
* Low-salt diet
* Reduced activity
* Rarely, a heart transplant may be needed.
