摘　　要：冠状动脉急性完全闭塞患者的心电图常表现为ST段抬高,容易早期发现和及时行血运重建治疗。在临床实践中发现,部分急性心肌梗死患者罪犯血管完全闭塞,常规心电图上却无典型的ST段抬高,即表现为非ST段抬高心肌梗死。这种现象在左回旋支急性完全闭塞的患者中更为常见,延迟了再灌注治疗时间,具有较高的心血管事件发生率和死亡率。因此,总结左回旋支急性完全闭塞的非ST段抬高心肌梗死患者的临床及心电图特点,对早期识别、尽早行血运重建、改善预后具有重要意义。The electrocardiogram(ECG)of patients with acute total occlusion of coronary artery usually presents ST segment elevation,which is easy to be detected for performing prompt revascularization.It has been found in clinical practice that some patients with acute myocardial infarction have completely occluded coronary artery,but there is no typical ECG ST segment elevation.That is non-ST segment elevation myocardial infarction.This is more common in patients with acute complete occlusion of the left circumflex artery.It delayed reperfusion treatment time and had a higher incidence of major adverse cardiac event and higher mortality.Therefore,to summarize the clinical and ECG features in this sub-group patients is of great significance for early identification,prompt reperfusion therapy and improved prognosis.
