摘要： 【摘要】 目的 研究 T波峰-末间期（Tp-Te 间期）和 Tp-Te 间期离散度（Tp-Ted）在急性心肌梗死（AMI）患者心肌缺血不同时期的变化， 评价 Tp-Te 间期和 Tp-Ted 对预测 AMI 患者发生室性心律失常的临床价值。 方法 比较 80例 AMI患者急性期与恢复期的 Tp-Te 间期和 Tp-Ted， 观察其与心肌梗死不同时期的关系； 比较心梗后室性心动过速组（A 组）、室性早搏组（B 组）、无室性心律失常组（C 组）患者间 Tp-Te 间期和 Tp-Ted的差异， 分析其与室性心律失常发生的关系 。 结果 急性期 Tp-Te 间期和 Tp-Ted 分别为（125.22±17.70） ms 和（54.76±13.26） ms， 均较恢复期（113.84±17.37） ms 和（42.06±13.95） ms 明显延长； Tp-Te 间期和 Tp-Ted 在 A 组分别为（134.82±19.56） ms、（62.00±15.19）ms， 明显高于 B 组的（122.94±15.09）ms、（54.09±10.56）ms 和 C 组的（110.09±15.21）ms、（45.27±9.85）ms； B 组又高于 C 组。 结论 Tp-Te 间期和 Tp-Ted 在 AMI 急性期较恢复期延长； Tp-Te 间期及 Tp-Ted 是预测 AMI 患者发

Abstract: [Abstract]  Objective  To investigate the relationship of T peak-T end (Tp-Te) interval and Tp-Te interval dispersion (Tp-Ted) in different periods of myocardial ischemia in patients with acute myocardial infarction (AMI), and to assess the clinical significance of Tp-Te and Tp-Ted for prediction of the ventricular arrhythmia (VA). Methods   A total of 80 patients with AMI were enrolled in the study. The sizes and changes of Tp-Te and Tp-Ted were observed during the acute phase and recovery phase in patients. The differences of Tp-Te and Tp-Ted were compared between ventricular tachycardia group (A group), ventricular premature beats group (B group) and non- ventricular arrhythmia group (C group). Results   The values of Tp-Te and Tp-Ted were obviously longer in acute period [(125.22±17.70) ms and (54.76±13.26) ms] than those in recovery period[ (113.84±17.37) ms and (42.06±13.95)ms] (P＜ 0.01). The values of Tp-Te and Tp-Ted were significantly longer in A group[ (134.82±19.56) ms and (62.00±15.19) ms] than those in B [(122.94±15.09) ms and (54.09±10.56)ms ]and C group [(110.09±15.21) ms and (45.27±9.85) ms]. The values were higher in B group than those of C group. Conclusion   The Tp-Te interval and Tp-Ted prolongated in acute phase than those of recovery phase in patients with AMI. TpTe interval and Tp-Ted can be used as an important index to predict VA in patients with AMI.
