摘　　要：在儿童患者中心肌炎与遗传性长QT综合征(LQTS)在临床表现上有一定相似性,如晕厥,心电图ST-T改变及多种形式的心律失常等,加之这两种疾病都会有一些表现不典型的病例,所以使得许多LQTS被误诊为心肌炎。其实,只要仔细分析患者的心电图特征并测量QT间期,这两种疾病还是可以鉴别的,误诊的原因主要是因为许多首诊的儿科医生对LQTS这种疾病的认识还不够全面深入。基于此,现重温心肌炎诊断标准的基础上,概述了儿童心肌炎与LQTS的异同点以及主要鉴别指标。There are some clinical similarities between myocarditis and inherited long QT syndrome （LQTS）, such as syncope, ST-T abnormality on ECG and variety of arrhythmias in young patients. In addition, they both have some atypical cases that made many LQTS mis- diagnosed as myocarditis. In fact, after anatomizing ECG and measuring QT interval it should be able to distinguish these two diseases. The reason for misdiagnosis is lack of comprehensive knowledge for some pediatricians. This article summarized the similarities and differences between myocarditis and LQTS and identifying index based on reviewing of diagnosis criteria of myocarditis.
