摘要
目的:探究体表心电图定位诊断急性下壁心肌梗死的应用价值。方法:纳入2017年4月~2019年3月本院收治的100例急性下壁心肌梗死患者为观察对象,所有患者均应用体表心电图检查,回顾分析心电图检查结果资料。结果:右冠状动脉(RCA)罪犯血管ST段抬高Ⅲ/Ⅱ>1,左冠状动脉回旋支(LCX)罪犯血管ST段抬高Ⅲ/Ⅱ≤1。RCA闭塞存在明显IaVL导联ST段下移,LCX闭塞则主要是IaVL无下移或抬高;不同闭塞部位患者STV3下移/STⅢ升高比值有明显差异性(P<0.05),存在统计学意义。结论:体表心电图能够用于急性下壁心肌梗死的定位诊断,便于依据确定的罪犯血管为患者治疗提供依据。
Objective: To explore the value of electrocardiographic localization in the diagnosis of acute inferior myocardial infarction. Methods: From April 2017 to March 2019, 100 patients with acute inferior wall myocardial infarction were treated in our hospital. All patients were examined with body surface ECG, and the results of ECG were analyzed retrospectively. Results: ST segment elevation of right coronary artery(RCA) and left circumflex coronary artery(LCX) was more than 1 and less than 1 respectively. There was significant ST segment depression in lead iavl in RCA occlusion, but no depression or elevation in lead iavl in LCX occlusion;there was significant difference in the ratio of STV3 depression/St Ⅲ elevation in patients with different occlusion sites(P<0.05). Conclusion: The surface electrocardiogram can be used for the location diagnosis of acute inferior wall myocardial infarction, which is convenient for the determination of culprit blood vessels to provide basis for the treatment of patients, and it is worth popularizing.
