摘要
目的:探讨室速患者T波峰末间期(T peak-T end interval,TPe)、T波峰末间期离散度的临床意义。方法:对36例室速患者及40例非室速患者分别测量同步12导联动态心电图的TPe间期,计算出TPe离散度(最长TPe与最短TPe之差)及其心率校正值。结果:室速组的TPe/RR、TPe离散度/RR较非室速组明显延长(P<0.01)。结论:室速患者TPe间期、TPe离散度延长有显著统计学意义。提示TPe间期、TPe离散度延长与室速的发生有密切关系。
Objective：To evaluate the role of T peak-T end interval （Tpe） and its dispersion in patients with ventricular tachycardia.Methods：Thirty-six patients with ventricular tachycardia （ventricular tachycardia group） and thirty patients without ventricular tachycardia （control group） were enrolled.Their Tp-Te intervals were calculated on twelve-ambulatory electrocardiograms in the two groups.Results：Tpe was （115.82±19.45） ms in ventricular tachycardia group,and （83.09±16.48） ms in control group,Tp-Te dispersion was （58.97±16.22） ms in ventricular tachycardia group,and （30.98±14.88） ms in control group.Both Tp-Te interval and Tp-Te dispersion showed a statistically significant difference in the two groups （P0.01）.Conclusion：The change of Tp-Te interval and Tp-Te dispersion may be a forecast factor whether induced ventricular tachycardia.
