目的:右室心肌梗死心电图诊断新标准的诊断价值。方法:回顾分析23例ⅡⅢ导联 ST 段抬高的急性下壁心肌梗死心电图,其中17例确诊合并右室心肌梗死,分析急性下壁心肌梗死 STⅢ/Ⅱ>1对右室心肌梗死的临床诊断价值。结果:急性下壁心肌梗死ⅡⅢ导联 ST 段抬高,STⅢ/Ⅱ>1对诊断右室心肌梗死的特异性较高。结论:急性下壁心肌梗死ⅡⅢ导联 ST 段抬高 STⅢ/Ⅱ>1可作为诊断右室心肌梗死的新标准。
Objective: The diagnostic value of a new standard of electrocardiogram diagnosis of right ventricular myocardial infarction. Methods: The electrocardiogram of acute inferior wall myocardial infarction with ST segment elevation in Ⅱ Ⅲ lead was retrospectively reviewed. Among them, 17 cases were diagnosed with right ventricular myocardial infarction. The clinical diagnosis of right ventricular myocardial infarction by ST Ⅲ / Ⅱ> 1 in acute inferior wall myocardial infarction value. Results: ST segment elevation was found in Ⅱ III lead of acute inferior myocardial infarction. The specificity of ST Ⅲ / Ⅱ> 1 in diagnosing right ventricular myocardial infarction was higher. Conclusion: ST Ⅲ / Ⅱ> 1 in type Ⅱ leads of acute inferior myocardial infarction can be used as a new standard in the diagnosis of right ventricular myocardial infarction.
