摘　　要：目的探讨直接经皮冠脉介入治疗(PCI)对急性心肌梗死(AMI)患者QT离散度(QTd)的影响。方法选择82例成功实施了直接PCI术的AMI患者为观察组,选择64例冠状动脉造影检查正常的患者为对照组,分别记录术前、术后心电图,计算各时期的QTd及QTcd。结果观察组病人术前QTd及QTcd显著大于对照组(P<0.05);观察组病人成功PCI术后与术前比较,QTd及QTcd显著缩短(P<0.05)。结论AMI患者QTd及QTcd显著高于正常人,成功的直接PCI可使患者QTd及QTcd明显缩短。Objective To study the effect of direct percutaneous coronalT intervention（PCI） on QT interval dispersion（QTd） and corrected QTd（QTcd） of patients with acute myocardial infarction（AMI）. Methods QTd and QTcd in 82 cases of （AMI） before and after successful primary PCI were measured and compared with those of 64 normal controls. Results Compared with the controls QTd and QTcd in patients with （AMI） before direct PCI were significantly increased （ P 〈 0. 05 ） and sigificantly reduced after direct PCI （ P 〈 0. 05 ）. Conclusions The QTd and QTcd of the patients with AMI are longer significantly than that of normal people,but they may become shorter as the direct PCI had been successfully made in these patients.
