摘要
目的:探讨急性心肌梗死(AMI)患者QT间期离散度(QTd)、JT间期离散度(JTd)与室性心律失常的关系.方法:测量63例AMI患者首次心电图的QTd及JTd,比较有室性心律失常组与无心律失常组的QTd、JTd.结果:AMI有室性心律失常组QTd及JTd显著高于无室性心律失常组,QTd(112.86±33.84)ms对(54.48±24.43)ms,JTd(101.43±36.34)ms对(41.38±19.22)ms,P<0.01.结论:QTd或JTd增大时发生室性心律失常的可能性增大.
Objective：To explore the releationship between QT/JT dispersion（QTd/JTd） and ventricular arrhythmia in patients with acute myocardial infarction. Methods：We measured QTd and JTd on the first electrocardiogram in 63 patients with acute myocardial infarction （AMI）, Results：QTd and JTd were greater in patients with ventricular arrhythmia than without ventricular arrhythmin. QTd （112.86±33.84）ms vs, （54. 48±24. 43）ms,P（0.01. JTd （101.43±36.34）ms vs. （41.38±19.22）ms,P〈0. 01. Conclusions： QTd or JTd augmentation may be associated with ventricular arrhythmia.
