Myocarditis is most often due to a viral infection
A large number of causes of myocarditis have been identified, but often a cause cannot be found
Myocarditis refers to an underlying process that causes inflammation and injury of the heart.
It does not refer to inflammation of the heart as a consequence of some other insult
The ECG findings most commonly seen in myocarditis are diffuse T wave inversions;
The gold standard is the biopsy of the myocardium, in general done in the setting of angiography.
A small tissue sample of the endocardium and myocardium is taken and investigated.
The cause of the myocarditis can be only diagnosed by a biopsy.
