- a friction rub may be present from pericarditis
Laboratory
- serum creatine kinase MB may be markedly elevated
- serum troponin I may be markedly elevated
Diagnostic procedures
- electrocardiogram
- ST segment elevation concave downward akin to MI[1]
- echocardiogram
- ventricular wall motion abnormalities
Radiology
