Significant ST-segment changes raise concern for myocardial ischemia, cardiomyopathy or myocardial inflammation and therefore, warrant an extensive and often invasive cardiovascular evaluation. We report a 12 year-old asymptomatic African-American girl with marked ST-segment elevation in leads I and aVL and ST-segment depression in inferior leads II, III and aVF. Extensive cardiovascular evaluation did not reveal any abnormality suggesting that these findings, which have previously not been reported, are likely benign, at least in this young girl.

无症状的12岁女孩的ST段外侧明显抬高伴ST段下压降低：正常吗？

ST段的显着改变引起了对心肌缺血，心肌病或心肌炎症的关注，因此，需要进行广泛且经常是侵入性的心血管评估。我们报告了一个12岁无症状的非洲裔美国女孩，I线和aVL线中ST段明显升高，II，III线和aVF线中ST段压低。广泛的心血管评估并未发现任何异常现象，这表明这些发现（以前从未报道过）可能是良性的，至少在这个年轻女孩中。
