Early ventricular repolarization as a probable consequence of acute viral and idiopathic myopericarditis

64 patients who had acute viral or idiopathic myopericarditis (40 males and 24 females aged 16-48 years) were followed up for 3 to 24 years. Echocardiography has found thickening of the pericardium from 5 to 8 mm which corresponded to fibrosis in 55 patients (85.9%). Early repolarization was detecte...

Summary:64 patients who had acute viral or idiopathic myopericarditis (40 males and 24 females aged 16-48 years) were followed up for 3 to 24 years. Echocardiography has found thickening of the pericardium from 5 to 8 mm which corresponded to fibrosis in 55 patients (85.9%). Early repolarization was detected in 17 patients, in 14 of them it was associated with pericardial thickening (82.4%). Of 30 healthy controls, early repolarization in combination with pericardial fibrosis occurred in 6.7% of cases. In 7 patients with early repolarization ECG registered residual changes of the acute period, in 6 new changes arose--His block and left ventricular hypertrophy. It is suggested that in many cases early repolarization is not independent, it is sequelae of previous myopericarditis.
