急性ST段抬高心肌梗死急诊介入术中再灌注心律失常的临床特点分析

目的分析急性ST段抬高心肌梗死（STEMI）患者急诊经皮冠状动脉介入术中（PCI）再灌注心律失常的临床特点。方法回顾性分析我院收治的经急诊PCI治疗的STEMI患者112例，分析再灌注心律失常的种类、再灌注心律失常与梗死相关动脉的关系以及与发病至冠脉再通时间之间的关系。结果STEMI急诊PCI中再灌注心律失常发生率为48．21％。前降支闭塞引起的再灌注心律失常以快速型心律失常为主，右冠状动脉及回旋支闭塞以缓慢型心律失常为主。梗死后6h内开通冠状动脉者再灌注心律失常发生率高于6h以上开通者（P〈0．05）。结论再灌注心律失常是STEMI患者行急诊PCI的常见并发症，其类型与梗死相关动脉及冠脉再通时间有关。

Analysis of Clinical Characteristics of Reperfusion Arrhythmia in Acute ST Segment Elevation Myocardial Infarction Undergoing Emergency Percutaneous Coronary Intervention

Objective To analyze the clinical characteristics of reperfusion arrhythmia in the ST segment elevation acute myocardial infarction （STEMI） undergoing emergency percutaneous coronary intervention （PCI）. Methods A retrospective analysis of our hospital 112 cases of emergency PCI in patients,to analyze the relationship between the species, reperfusion arrhythmia and related artery reperfusion arrhythmia and myocardial infarction and coronary recanalization time from onset to. Results STEMI emergency PCI of reperfusion arrhythmia incidence was 48.21%. Anterior descending artery infarction reperfusion arrhythmia in cardiac arrhythmia, right coronary artery and circumflex artery infarction with slow arrhythmia. Infarction within 6h after the opening of coronary artery reperfusion arrhythmia incidence rate is above 6 h open（P〈0.05）. Conclusion Reperfusion arrhythmia is a common complication of STEMI patients undergoing PCI,its related artery type and infarction and reperfusion time.
