The supersound aroused in interest is pursued to usually change into cardiac dilatation, ventricle skin regionality or disseminated and moved unusually. Acute issues of about half the disease erythrocyte sedimentation rate increase fast, serum creatine phosphokinase isoenzyme (CK-MB) Rise with myocardium calcium albumen T density.
The clinical symptom of the viral myocarditis has the characteristics that the weight intensity is widely different, the symptom displays and often lacks peculiar typicality. Nearly have half the number patient before having illness coming on (about 1 week- 3 weeks) Upper airway infection and digestive tract infect the history.
