Pericarditis or myocarditis: still a clinical problem

Pericarditis and myocarditis are diseases of a similar etiology and clinical image, and they often overlap. Depending on the clinical manifestation, there is pericarditis with simultaneous involvement of the heart muscle (myopericarditis), or myocarditis with pericardial involvement (perimyocarditis). The paper presents a case of a young patient with myopericarditis, with attention to the electrocardiographic image and parameters of myocardial damage.
