摘要
目的:探讨急性心肌梗死(AMI)恢复期心电图QT离散度(QTD)变化与AMI晚发室性心律失常(DVA)的关系。方法:128例AMI病人(男81例,女47例)中入院时心律失常组32例,无心律失常组96例。分别于入院时及入院第3周做心电图测量QTD。结果:AMI组QTD<60ms的82例中9.8%发生室性心律失常;>60ms而<100ms的37例中40.5%(15/37)发生室性心律失常;>100ms者100%发生室性心律失常。结论:AMI病人治疗过程中QTD愈大,DVA发生率愈高。
Objective To study the relation between the changes of dispersion degree of QT in electrocardiagram and later ventricular tachyarrhythmias of AMI. Methods Among 128 patients （including 81 men and 47 women）with AMI, 32 patients had tachyarrhythmias and 96 no tachyarrhythmias. All the patients were examined electrocardiagram and measured QTD upon entry into the hospital and three weeks later. Results Among 82 patients with QTD smaller than 60 ms,9.8% had ventricular tachyarrhythmias of 37 patients with QTD larger than 60 ms but smaller than 100ms,40.5%（15/37） had ventricular tachyarrhythmias and all the patients with QTD larger than 100 ms had ventricular tachyarrhythmias. Conclusions In the incidence of DVA.
