心电图Tp-Te间期、Tp-Te/QT比值与恶性室性心律失常的关系

Relationship among Tp-Te interval and ratio of Tp-Te to QT in ECG and malignant ventricular arrhythmia

目的探讨心电图T波峰末间期(Tp-Te)、Tp-Te/QT比值对恶性室性心律失常(MVA)的诊断价值。方法连续入选2017年1月1日至2018年1月1日于保定市第一中心医院西院心电图、脑电图二室行24 h 12导联动态心电图检查的患者412例为研究对象。根据是否发生恶性室性心律失常分为两组:恶性室性心律失常组72例;无恶性室性心律失常组340例。分别测定两组患者Tp-Te间期、QT间期,计算出Tp-Te间期、QTc间期及Tp-Te/QT比值,并对两组患者Tp-Te间期、QTc间期及Tp-Te/QT比值进行统计学分析。结果恶性室性心律失常组的Tp-Te间期、Tp-Te/QT比值均较非恶性室性心律失常组明显增加(P<0.001)。结论Tp-Te间期、Tp-Te/QT比值增加对于恶性室性心律失常的发生均有预测价值。

Objective To investigate the diagnostic value of Tp-Te interval(Tp-Te)and ratio of Tp-Te to QT(Tp-Te/QT)in ECG to malignant ventricular arrhythmia(MVA).Methods The patients(n=412)received 24 h 12-lead ambulatory electrocardiograph monitoring were continuously chosen from Rooms of Electrocardiogram and Electroencephalogram in the First Center Hospital of Baoding City from Jan.1,2017 to Jan.1,2018.According to whether they had MVA or not,all patients were divided into MVA group(n=72)and non-MVA group(n=340).Tp-Te and QT were measured,and Tp-Te,QTc and Tp-Te/QT were calculated and given statistical analysis.Results Tp-Te and Tp-Te/QT increased significantly in MVA group than those in non-MVA group(P<0.001).Conclusion Increased Tp-Te and Tp-Te/QT have some predictive value to MVA incidence.
