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 relationship between T wave peak (Tp-Te) and Tp-Te interval (Tp-Tec) in acute myocardial infarction (AMI) patients with acute ventricular arrhythmias the value of. Methods: A total of 367 patients with AMI were enrolled in Nanjing Hospital Affiliated to Nanjing Medical University from December 2014 to July 2016. Among them, 198 cases of ventricular arrhythmias (ventricular arrhythmia group) and no ventricular arrhythmias 169 Cases (no ventricular arrhythmia group). All patients were tested for Tp-Te, Tp-Tec. Results: The levels of Tp-Te and Tp-Tec in the ventricular arrhythmia group were (135.22 ± 18.86), (113.81 ± 12.80) ms and (126.10 ± 18.06) and (110.16 ± 9.89) ms, respectively, Tp-Te and Tp-Tec in convalescent ventricular arrhythmia group and non-ventricular arrhythmia group were lower than those in acute phase (P <0.05). The anterior wall, inferior posterior wall And multi-site AMI patients Tp-Te, Tp-Tec no significant difference (P> 0.05). There were 14 death cases (7.08%) and 4 cases (2.37%) in ventricular arrhythmia group and non-ventricular arrhythmia group, respectively. The difference was statistically significant (χ ~ 2 = 4.325, P = 0.038). The remaining patients survived and were discharged. Conclusion: The changes of Tp-Te and Tp-Tec in electrocardiogram have some value in the diagnosis of ventricular arrhythmia in AMI. However, further study is required.
