摘要
目的评价ST段偏移模式对急性心肌梗死罪犯血管、罪犯病变部位的预测效果。方法对完成介入手术的急性心肌梗死患者(分为下壁和前壁)判断罪犯血管、罪犯病变部位以及分析各导联ST段偏移特点,并对相关性进行分析。结果在急性下壁心肌梗死患者中,ST_Ⅲ抬高程度＞ST_Ⅱ以及ST_(Ⅰ、aVL)导联压低＞1 mm预测右冠罪犯病变具有良好的敏感性(75%)和特异性(100%)。对于前壁心肌梗死患者,ST_(Ⅱ、Ⅲ、aVF)压低＞1 mm预测前降支近段罪犯病变敏感性(39%)稍差,但特异性(93%)良好。结论心电图是判断罪犯血管和罪犯病变重要、可行的方法。
Objective To study ST-segment deviation on predicting culprit artery or culprit lesion in acute myocardial infarction （AMI）. Methods The study population included patients with AMI who subsequently underwent coronary angiography during hospitalization. Culprit artery and culprit parts were evaluated, and ST- segment characteristics were analyzed. Results A higher ST-segment elevation in lead Ⅲ than in lead Ⅱ and ST-segment depression 〉 1 mm in lead aVL or lead Ⅰ were highly sensitive （75%） and specific （100%） markers for right coronary artery-related AMI. ST-segment depression 〉 1 mm in lead Ⅱ, Ⅲ and aVF was lowly sensitive （39%） and highly specific （93 % ） marker for the left anterior descending artery-related AMI. Conclusion The culprit artery or culprit lesion could be predicted by using electrocardiogram at admission.
