Abstract：
Identifying the infarct-related artery (IRA) in a non-ST-segment-elevation acute myocardial infarction (NSTEMI) can be very challenging, particularly in a hospital that cannot perform intracoronary imaging due to certain limitations. This is because, by angiography, most patients present with multivessel coronary artery disease (CAD), diffuse disease, or non-significant CAD. We present a case of a 60-year-old female patient presented with substernal chest pain and palpitations of 6 h duration. The first hospital contact 12-lead electrocardiogram (ECG) showed ventricular tachycardia (VT) with unstable hemodynamics, after stabilization patient was transported to the catheterization laboratory for immediate percutaneous coronary intervention (PCI). With a clue of VT morphology, post-converted ECG, and coronary angiography, the patient successfully underwent PCI in the left circumflex artery.
摘要：
识别非ST段抬高型急性心肌梗死（NSTEMI）的梗死相关动脉（IRA）可能非常具有挑战性，特别是在由于某些限制而无法进行冠状动脉成像的医院中。这是因为,通过血管造影，大多数患者出现多支冠状动脉疾病（CAD），弥漫性疾病,或非显著的CAD。我们介绍了一例60岁的女性患者，其胸骨下胸痛和心悸持续6小时。第一医院联系12导联心电图（ECG）显示室性心动过速（VT），血流动力学不稳定，稳定后,患者被送往导管插入实验室进行立即经皮冠状动脉介入治疗(PCI).有了室性心动过速形态学的线索,转换后的心电图,和冠状动脉造影，患者成功在左回旋支动脉行PCI.
