摘要:

目的:探讨急性心肌梗死(AMI)患者12导联体表心电图中T波峰末间期(Tpe)测量的最佳导联。方法： 纳入2011~2013年来我院心内科就诊的AMI患者232例，并选取同期在本院行健康体检的200例正常人作为对照组，分别测量两组中全部导联的Tpe值并进行比较。结果： AMI组中V2导联的Tpe值最大，与其它各导联上的Tpe值两两比较差异均有统计学意义(P<0.05)；对照组中V2导联的Tpe值，除与V3导联无统计学差异外，均大于其它导联（P<0.05）。AMI组中各导联的Tpe值均大于对照组相应导联的Tpe值［(113±16) ms vs.(87±18) ms,P<0.05］。结论： 在AMI患者和正常人中，测量和分析T波峰末间期时，选择胸前区导联可能更具可靠性、稳定性。

Abstract:

AIM:To investigate the lead selection of the T peak-T end interval (Tpe) in patients with acute myocardial infarction (AMI). METHODS: Two hundred and thirty-two AMI patients and 200 normal control subjects were enrolled. The standard 12-lead electrocardiogram was recorded in all subjects to determine the optimal lead for Tpe measurement. RESULTS: The Tpe value in V2 lead was the greatest in AMI patients compared with those of other leads (P<0.05). The Tpe in V2 lead in control group was greater than those of other leads (P<0.05) except for V3 lead. The Tpe values of all leads in AMI group were greater than those of corresponding leads in control group (112.78 ms vs. 87.36 ms, P<0.05). CONCLUSION: V2 may be selected as the optimal lead to reflect the maximal Tpe.
