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.
