【摘要】：目的:对急性下壁心肌梗死患者的心电图资料进行回顾性研究，分析和比较心电图改变与冠状动脉造影及临床特点的对应性关系。探讨急性下壁心肌梗死患者的体表心电图对梗死相关血管及闭塞部位的预测价值。方法:选取86例急性下壁心肌梗死患者，根据冠状动脉造影结果分为右冠状动脉(RCA)病变组和左冠状动脉(LCA)病变组。对比分析其心电图改变与冠状动脉造影结果及临床特点。结果:（1）本文研究提示造影显示正常冠状动脉者均不合并糖尿病，急性下壁心肌梗死合并糖尿病患者中双支、多支血管病变居多；年龄越大，，累及病变血管支数越多。（2）急性下壁心肌梗死患者IRA为LCX者均为男性患者；后壁、右室心肌梗死常与下壁心肌梗死并存；并发右室梗死者，其IRA均为RCA，且病变节段均位于右冠状动脉近段；冠状动脉造影正常者均为单纯急性下壁心肌梗死，并未合并其它部位心肌梗死。（3）通过ST↓aVL＞ST↓I指标判断IRA为RCA病变检出率高。（4）不同导联ST偏移标准判断IRA为RCA或LCX的灵敏度、特异度均不高。（5）对所有下壁心肌梗死患者，均应该及时准确地记录右胸导联心电图。结论:心电图对诊断下壁急性心肌梗死相关血管及其临床特点具有重要的预测价值。
[Abstract]:Objective: to study the electrocardiogram data of patients with acute inferior wall myocardial infarction (AMI). To analyze and compare the corresponding relationship between electrocardiogram changes and coronary angiography and clinical features. To explore the predictive value of surface electrocardiogram in patients with acute inferior wall myocardial infarction on infarct-related vessels and occlusion sites. 86 patients with acute inferior wall myocardial infarction, According to the results of coronary angiography, the patients were divided into two groups: right coronary artery lesion group (RCA) and left coronary artery lesion group (LCA). The electrocardiogram changes, coronary angiography results and clinical characteristics were compared and analyzed. Patients with normal coronary artery were not complicated with diabetes, In the patients with acute inferior wall myocardial infarction complicated with diabetes mellitus, the patients with IRA were male, the patients with IRA were male, the patients with IRA were male, the patients with acute inferior wall myocardial infarction complicated with diabetes mellitus, the patients with multiple vessel disease were mostly; the older the age, the more the number of branches involved in the lesion. Right ventricular myocardial infarction often coexisted with inferior myocardial infarction. The IRA of patients complicated with right ventricular infarction were all located in the proximal segment of right coronary artery, and those with normal coronary angiography were all simple acute inferior myocardial infarction. No other myocardial infarction. 鈫揂VL > St. 鈫揟he sensitivity and specificity of different lead St deviation criteria in judging whether IRA was RCA or LCX was not high. 5) in all patients with inferior myocardial infarction, the detection rate of IRA was high. Conclusion: electrocardiogram (ECG) has important predictive value in the diagnosis of inferior wall acute myocardial infarction (AMI) related blood vessels and its clinical characteristics.
