摘要
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。
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.
