[Problems of the clinical diagnosis of myocarditis].

Anamnesis, clinical findings, changes of the ECG, findings of X-ray examinations and biological reactions in 39 patients with myocarditis are discussed. For the diagnosis of myocarditis are discussed. For the diagnosis of myocarditis changes of the ECG, enlargement of the heart, cardiac insufficiency and disturbances of rhythm are of greatest importance. Changes in the ST-T-segment are non-specific. An exact anamnesis and a comparison with previous findings (X-ray serial examination, ECG) may give decisive hints. Biological reactions are often unreliable in making the diagnosis. There are no typical symptoms and findings for the diagnosis of the inflammatory disease of the myocardium. In the individual case the diagnosis of a myocarditis may be a tentative or excluded diagnosis.
