摘要
目的:探讨心电图T波峰-末间期(Tp-Te)、经心率校正的Tp-Te间期(Tp-Tec)在诊断急性心肌梗死(acute myocardial infarction,AMI)患者发生急性期室性心律失常的价值。方法:选取2014年12月至2016年7月在南京医科大学附属南京医院治疗的AMI患者367例,其中急性期发生室性心律失常198例(室性心律失常组),无室性心律失常169例(无室性心律失常组)。检测所有患者的Tp-Te、Tp-Tec。结果:室性心律失常组急性期和恢复期Tp-Te、Tp-Tec分别为(135.22±18.86)、(113.81±12.80)ms及(126.10±18.06)、(110.16±9.89)ms,明显高于无室性心律失常组(P<0.05);室性心律失常组和无室性心律失常组恢复期Tp-Te、Tp-Tec均较急性期降低(P<0.05);前壁、下后壁及多部位AMI患者Tp-Te、Tp-Tec比较差异无统计学意义(P>0.05)。室性心律失常组和无室性心律失常组分别死亡14例(7.08%)、4例(2.37%),差异有统计学意义(χ~2=4.325,P=0.038)。其余患者生存并恢复出院。结论:心电图Tp-Te、Tp-Tec变化在诊断AMI发生室性心律失常中有一定的应用价值,但须进一步研究。
Objective：To investigate the value of T peak end interval（Tp-Te） and Tp-Tec interval corrected by heart rate（Tp-Tec） in the diagnosis of ventricular arrhythmia in acute myocardial infarction（AMI） patients.Methods：367 AMI patients in our hospital from February 2013 to July 2016 were collected and divided into 198 cases ventricular arrhythmia（ventricular arrhythmia group） in acute stage and 169 cases non ventricular arrhythmia（non ventricular arrhythmia group）.Tp-Te and Tp-Tec in all patients were observed and compared within the groups.Results：Tp-Te and Tp-Tec in ventricular arrhythmia group acute stage and recovery stage were（135.22±18.86） ms and（113.81±12.80） ms,（126.10±18.06） ms and（110.16±9.89） ms,respectively,both were significantly higher than that of non ventricular arrhythmia group（P〈0.05）.Tp-Te and Tp-Tec in the recovery stage of ventricular arrhythmia group and non ventricular arrhythmia group were lower than those in the acute stages in the two groups（P〈0.05）.There had no significant differences in Tp-Te and Tp-Tec between anterior wall,lower posterior wall and multiple sites of myocardial infarction（P〉0.05）.The deaths in the ventricular arrhythmia were more than the non ventricular arrhythmia group（P〉0.05）.Conclusion：Tp-Te and Tp-Tec have certain applicable value in the diagnosis of ventricular arrhythmia caused by AMI,which still needs further study.
