目的:探索体表十二导联心电图ST aVR抬高及ST aVR/STV 1抬高≥1预测左主干急性闭塞诱发前壁心肌梗死中的价值。方法:2003-08/2008-04本院确诊为急性前壁心肌梗死的120例患者,据经冠脉造影结果分为左主干闭塞组(LM组)38例;前降支闭塞组(LAD组)82例,计算并比较两组十二导联心电图aVR导联的ST段抬高及ST aVR/STV 1抬高≥1比例。结果:与LAD组比较,LM组ST aVR抬高例数显著增高(0.16±0.10 vs 0.05±0.06,P<0.05),且ST aVR/STV 1抬高≥1例数,LM组也显著增高(0.16±0.21 vs-0.09±0.11,P<0.01)。结论:十二导联心电图中检测ST aVR抬高及ST aVR抬高/STV 1抬高≥1有助于鉴别诊断前壁AM I患者中LM闭塞或LAD闭塞。
OBJECTIVE: To explore the value of ST aVR elevation of ST-12 lead electrocardiogram and ST aVR / STV 1 elevation of ≥1 in predicting acute left main occlusion-induced anterior myocardial infarction. METHODS: One hundred and twenty patients diagnosed as acute anterior myocardial infarction in our hospital from August 2003 to April 2008 were divided into three groups: the left main occlusion group (LM group), 38 cases; the left anterior descending artery occlusion group (LAD group) ) 82 patients were enrolled in this study. The ST segment elevation and the ST aVR / STV 1 elevation ≥1 in the aVR lead of the 12-lead ECG were calculated and compared. Results: Compared with LAD group, the number of elevated ST aVR in LM group was significantly higher than that in LAD group (0.16 ± 0.10 vs 0.05 ± 0.06, P <0.05), and ST aVR / STV 1 elevation was> 1 in LM group 0.16 ± 0.21 vs-0.09 ± 0.11, P <0.01). CONCLUSIONS: Elevated ST aVR and ST aVR elevation / STV 1 elevation ≥ 1 in the 12-lead electrocardiogram may be useful in differential diagnosis of LM occlusion or occlusion of LAD in patients with AMI in the anterior wall.
