大多数感染性心肌炎为轻型,容易误诊或忽略。Heikkila等复习一组185例在急性感染性疾病期间因心电图异常而住院的患者,并随访12个月以上。本组患者年龄为18～38(中数20)岁,全部均<40岁因而未必可能包括许多缺血性心脏病患者。心肌心包炎通常发生在急性呼吸道感染后1～2周,且类 Most infectious myocarditis is light and easily misdiagnosed or overlooked. Heikkila et al reviewed a group of 185 patients hospitalized for ECG abnormalities during acute infectious disease and were followed up for more than 12 months. This group of patients aged 18 to 38 (median 20) years old, all <40 years old and therefore may not necessarily include many ischemic heart disease patients. Myocardial pericarditis usually occurs 1 to 2 weeks after acute respiratory infection, and the class
