急性心肌梗死后QT离散度与室壁瘤的关系

Relationship of QT dispersion and ventricular aneurysm after acute myocardial infarction

目的:探讨QT离散度(QTd)与急性心肌梗死(AMI)并发室壁瘤的关系。方法:按世界卫生组织(WHO)诊断标准,将我院2003～2006年收治的AMI患者60例进行回顾性分析。结果:发生室壁瘤29例,未发生室壁瘤31例,比较两组体表12导联心电图的QTd。两组QTd差异有统计学意义(P<0.01)。结论:AMI患者QTd增加时易发生室壁瘤,提示QTd是预测AMI患者发生室壁瘤的一种简单可靠的方法。

Objective：To study the relationship of QT dispersion and left ventricular aneurysm in the patients with acute myocardial infarction.Methods：According to the World Health Organization（WHO） diagnostic criteria,in our hospital from 2003 to 2006,treated 60 patients with acute myocardial infarction were retrospectively studied.Results：29 cases of aneurysm occurred.No aneurysm occurred in 31 cases.Comparing QTd of surface 12-lead ECG between the two groups,there was statistically significant difference in QTd（P〈0.01）.Conclusion：QTd in the patients with acute myocardial infarction increases aneurysm-prone,suggesting that QTd in the patients with acute myocardial infarction may be as a simple and reliable method to predict left ventricular aneurysm occurring.
