摘　　要：目的 :探讨急性下壁心肌梗死 (AIMI)时 ,V7～ 9导联 ST段抬高对判断梗死相关动脉 (IRA)、梗死范围及近期愈后的作用。方法 :对 146例 AIMI患者的心电图及有关临床资料进行分析。结果 :与单纯 AIMI患者相比较 ,AIMI伴 V7～ 9导联 ST段抬高的患者中回旋支为 IRA的比例较高 (40 .9% ,P <0 .0 2 5 )、CK峰值高 (P <0 .0 0 1) ,左心室功能差 (均 P <0 .0 0 1)、严重快速性心律失常及总的心脏事件发生率高 (P <0 .0 2 5～ 0 .0 0 5 )。结论 :V7～ 9导联 ST段抬高对判断 AIMI患者的 IRA。Objective:To investigate the value of STsegment elevations in posterior chest leads( V 7～9 ) in predicting the myocardial infarctrelated artery(IRA), the size of myocardial infarction and acute inhospital prognosis in patients with acute inferior myocardial infarction (AIMI).Method:146 patients with AIMI were studied.61 of them had STv 7～9 elevetion≥1 mm (group A).The STv 7～9 were not eleveted in other 85 cases (group B).Result:In comparison with those in group B patients,the percentage of left circumflex artery as IRA was higher (P< 0.025 ),peak level of CK was higher (P< 0.001 ) and left ventricular functions was poorer (P< 0.001 ) in group A patients. In addition, group A patients experienced a higher incidence of tachyarrhythmia and cardiac events (P< 0,025 ~ 0.005 ).Conclusion: STsegment elevations in posterior chest leads (V 7～9 ) in AIMI has significant value in predicting IRA ,size of myocardial infarction and acute inhospital prognosis.
