Abstract

We present two patients who were admitted to our Hospital because of repetitive syncopal attacks. The study previous to their admission included electrocardiograms in which the QT interval was normal. During their admission, an striking lengthening of the QT interval, in addition to other criteria of the long QT syndrome, was observed in both patients. We suggest that one normal measurement of the QT interval should not rule out this diagnosis.

摘要

我们报告了两名因反复晕厥发作而入住我院的患者。入院前的检查包括心电图，其QT间期正常。在住院期间，两名患者均出现QT间期显著延长，以及长QT综合征的其他标准。我们建议，单次QT间期正常测量结果不应排除该诊断。
