摘　　要：目的:探讨检测冠状动脉粥样硬化性心脏病(冠心病)并发室性心动过速(室速)患者T波峰末间期(Tpeak-Tend interval,Tp-Te间期)的意义。方法:分析46例发生室速(室速组)和23例无室速(非室速组)的冠心病患者的12导联同步动态心电图,测量2组的Tp-Te间期并进行比较。结果:室速组的Tp-Te间期为(114±26)ms,非室速组为(96±15)ms,2组比较差异有统计学意义(P(0.01)。Logistic回归分析显示,Tp-Te间期改变是冠心病并发室速患者的独立危险因素(比数比为0.95,P(0.01)。结论:对冠心病患者检测其Tp-Te间期的改变,可识别冠心病患者是否易诱发室速。Objective： To evaluate the role of detecting Tpeak-Tend interval （Tp-Te interval） in coro- nary heart disease with ventricular tachycardia patients. Methods： Forty-six patients with ventricular tachyeardia （ventficular tachycardia group） and twenty-three patients without ventricular tachycardia （no ventricular tachycardia group） were enrolled. Their Tp-Te intervals were calculated on twelve-ambulatory electrocardiograms in the two groups. Results： Tp-Te interval in ventricular tachycardia group was （114±26）ms, and was （96±15） ms in no ventricular tachycardia group, Tp-Te interval showed a significance difference in the two groups（P〈0.01）. Logistic regression analysis showed that the Tp-Te interval was the independent risk factor for coronary heart disease with ventricular taehycardia（P 〈 0. 01 ）. Conclusion： The change of Tp-Te interval is a forecast factor whether induced ventricular tachycardia in patients with coronary artery disease.
