Abstract：
We report a case of ST segment elevation in left precordial leads with a convex shape caused by a rare etiology. By carefully analyzing the electrocardiogram (leads I, II, V3 to V9) of a patient with convex ST segment elevation in the left-sided chest leads, relevant etiological clues were derived. The findings were further supported by cardiac ultrasound and cardiac magnetic resonance imaging, ruling out other common causes. Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) was postulated as the underlying cause, and potential mechanisms were discussed. The diagnosis was further confirmed through a follow-up period of over three years.
摘要：
我们报告了一例由罕见病因引起的左心前导联ST段抬高，呈凸形。通过仔细分析心电图（I导联，II,V3至V9）的患者，左侧胸导联中ST段抬高，得出了相关的病因线索。心脏超声和心脏磁共振成像进一步支持了这一发现。排除其他常见原因。心律失常性右心室心肌病（ARVC）被认为是根本原因，并讨论了潜在的机制。通过超过三年的随访期进一步证实了该诊断。
