摘要(Abstract)：

左冠状动脉异常起源于肺动脉是一种死亡率极高的疾病，大约90%的患者在出生后的第1年死于心肌梗死和心力衰竭，很少有患者在不做手术的情况下活到成年。而超过50岁的成人左冠状动脉异常起源于肺动脉就更为少见，可能表现为无症状、心绞痛、劳力性呼吸困难、心肌梗死和心原性猝死。而以室性心动过速为首发表现的病例报道更罕见。本文报道1例独特的病例，患者为58岁女性，既往体健，因胸闷、心悸症状持续不缓解于当地医院行心电图检查发现室性心动过速，心肌损伤标志物阴性。5 h后于本院急诊行心电图检查发现胸前导联Q波，ST-T改变，肌钙蛋白I明显升高，后行冠状动脉造影及冠状动脉CT血管造影检查发现左冠状动脉异常起源于肺动脉。
