摘要
目的 探讨ST段抬高型急性心肌梗死（STEMI）患者的T波峰末间期（T peak-T end interval,Tp-e）检测的临床意义.方法 分别测量63例STEMI患者（STEMI组）和60例健康对照者（正常对照组）的Tp-e,并计算经心率校正的T波峰末间期（Tp-e/R-R,TcPe）,并把STEMI患者分为室性心律失常组和非室性心律失常组,对比分析STEMI组和正常对照组,室性心律失常组和非室性心律失常组的Tp-e及TcPe.结果 STEMI组患者的Tp-e、TcPe与正常对照组比较,差异均有统计学意义（P＜0.01）;STEMI组中室性心律失常组的Tp-e、TcPe与非室性心律失常组比较,差异均有统计学意义 （P＜0.05）.结论 STEMI患者Tp-e、TcPe增大,表明STEMI患者心室肌跨壁复极离散度增大,易发生室性心律失常.
Objective To explore the clinical significance of detecting T peak - T end interval （ Tp - e ） in patients with ST elevation acute myocardial infarction （STEMI）. Methods Tp -e and heart rate -corrected Tp -e （TcPe） were compared between the STEMI group （n = 63 ） and the normal group （n = 60） ; Patients with STEMI were divided into ventrieular arrhythmia group and non - ventricular arrhythmia group, and Tp - e and TcPe were compared between the two groups. Results Tp - e and TcPe in patients with STEMI were significantly longer than those in normal group （ P 〈 0.01 ）. Tp - e and TcPe in ventricular arrhythmia group were significantly longer than that in non - ventricular arrhythmia group （ P 〈 0. 05 ）. Conclusion Tp -e and TcPe in patients with STEMI are obviously longer, which indicates the transmural dispersion of repolarization in pa- tients with STEMI is increased, so does the incidence of ventrieular arrhythmia.
