摘　　要：目的探讨冠心病患者心电图复极离散度的意义。方法非器质性心脏病对照组50例,冠心病组50例,描记两组的常规12导联心电图,测量QT间期(QT)、QTc间期(QTc)、QT离散度(QTd)、校正QT离散度(QTcd)、T波峰-T波末间期(Tp-Te)和T波峰-T波末间期离散度(Tp-Te间期离散度),并进行统计学分析。结果冠心病组Tp-Te间期、Tp-Te间期离散度与对照组相比均有延长(P<0.001)。结论 Tp-Te间期及Tp-Te间期离散度的延长对预测危险室性心律失常有一定意义。Objective To analyze the significance of ECG repolarization dispersion in patients with coronary heart disease.Methods The QT interval,QTc interval,QT dispersion（QTd）,corrected QT dispersion（QTcd）,Tpeak-Tend interval（Tp-Te）and Tpeak-Tend interval dispersion（Tp-Te Interval dispersion）in the 12 leads of electrocardiograms were measured and compared in 50 patients with coronary heart disease（CHD group）and 50 health people（control group）.Results Tp-Te interval dispersion in CHD group was longer than that in control group（P0.001）. Conclusion The Tpeak-Tend interval and Tpeak-Tend interval dispersion extension have certain significance to predicting dangerous ventricular arrhythmia.
