摘　　要：目的探讨急性心肌梗死患者体表心电图T波峰-末间期(Tp-Te)、经心率校正的Tp-Te间期(Tp-Tec)和Tp-Te间期离散度(Tp-Ted)与急性期室性心律失常发生的关系。方法分析我院治疗的50例急性心肌梗死(AMI)患者急性期与恢复期的Tp-Te、Tp-Tec和Tp-Ted,观察其与心肌梗死不同时期的关系。根据急性心肌梗死患者急性期是否发生过室性心动过速(VT)或心室颤动(VF))分为室性心律失常组(31例)和无室性心律失常组(19例),分析心肌梗死急性期发生室性心律失常组与无室性心律失常组Tp-Te、Tp-Tec和Tp-Ted的差别,分析Tp-Te及其相关指标与室性心律失常发生的关系。结果急性心肌梗死急性期的Tp-Te、Tp-Tec及Tp-Ted长于心肌梗死恢复期,差异具有统计学意义(P<0.05);Tp-Te、Tp-Tec及Tp-Ted与AMI患者急性期室性心律失常的发生率呈正相关(r=0.671,P<0.05;r=0.703,P<0.05;r=0.694,P<0.05)。结论 Tp-Te、Tp-Tec及Tp-Ted在AMI急性期较恢复期延长,Tp-Te、Tp-Tec及Tp-Ted可能成为预测AMI患者发生多种室性心律失常的一项重要指标。Objective To study the relationship between Teapk-Tend （Tp-Te）, corrected Tp-Te （Tp-Tec） and Tp-Te interval disper- sion （Tp-Ted） in surface electrocardiogram and ventricular arrhythmia during the acute phase of myocardial infarction. Methods A total of 50 patients with AMI treated in our hospital were enrolled in the study. The sizes and changes of Tp-Te, Tp-Tec and Tp-Ted were observed during the acute phase and recovery phase in patients. According to whether there had been acute myocardial infarction ventricular tachyeardia （VT） or ventricular fibrillation （ VF）, cases were divided into ventricular arrhythmia group （ 31 cases） and without ventricular arrhythmia group （19 cases）. Tp-Te intervals,corrected Tp-Te （Tp-Tec） and Tp-Ted were measured and compared between the two groups. The rela- tionship between Teapk-Tend （ Tp-Te）, corrected Tp-Te （Tp-Tec） and Tp-Te interval dispersion （Tp-Ted） and ventricular arrhythmia were analyzed. Results The values of Tp-Te, Tp-Tec and Tp-Ted were obviously longer in acute period than those in recovery period （P 〈 0.05）. The value of Tp-Te, Tp-Tec and Tp-Ted was positively correlated with the incidence of ventricular arrhythmia in the acute phase of myocardial infarction （r=0. 671,P〈0. 05;r=0. 703,P〈0. 05;r=0. 694,P〈0. 05）.Conelusion The Tp-Te,Tp-Tec and Tp-Ted were prolonged in the acute phase than those of recovery phase in patients with AMI. Tp-Te, Tp-Tee and Tp-Ted can be used as important indices to predict ven- tricular arrhythmia in patients with AMI.
