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 taehycardia group （A group）, ventricular premature beats group （B group） and non- ventrieular 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. Conclusion 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.
