　　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患者发生多种室性心律失常的一项重要指标。

Objective To investigate the relationship of T peak-T end (Tp-Te) interval and Tp-Te interval disper-sion (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 pa-tients 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 signifi-cantly 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. Con-clusion The Tp-Te interval and Tp-Ted prolongated in acute phase than those of recovery phase in patients with AMI. Tp-Te interval and Tp-Ted can be used as an important index to predict VA in patients with AMI.
