摘要
本文对80例急性下壁心肌梗塞和38例同时合并后侧壁心肌梗塞的心电图改变进行了对比分析,结果表明急性下壁心肌梗塞合并后侧壁梗塞患者胸前导联ST段较无后侧壁梗塞组下降明显,且与下壁导联ST段改变呈负相关(r=-0.772,P<0.01)。胸前导联ST段下降在合并后侧壁梗塞诊断中的敏感性为73.7%,特异性为75.0%,从而提示急性下壁心肌梗塞时如果有胸前导联ST段压低应注意是否合并后侧壁梗塞。另外,本组研究还表明左前降支和左旋支病变在急性下壁心肌梗塞合并后侧壁梗塞胸前导联ST段压低的发生中不起重要作用。
patients with inferior acute myocardial infarction(AMI) and 38 cases withinferior AMI
associated posterior wall infarction were studed to determine the ECG diagnosticvalue。 It was
shown the precordial ST segment depression in concomitant posterior wallinfarction was higher
than that in inferior AMI, and correlated highly with ST segmentchanges in inferior leads. The
results also indicated the precordial ST segment depressionwere both sensitive (73.7%)and
sepecific(75.0%)in indentifying associating posterior wall1. infarction。 In addition, cardiac
catheterization findings shown the vessel disease in left ant-erior descending artery and left
circumflex artery were no significance in the occurrance ofprecordial ST segment depression in
inferior and posterior AMI。
