摘要 [目的]探讨急性心肌梗死(AMI)患者心电图T波峰-末间期(Tp-Te间期)检测的临床意义.[方法]选取41例AMI患者作为观察组,40例正常健康者为对照组,并将观察组患者在急性期有无发生室性心律失常分为两组.测量正常健康者体检时及AMI患者入院24 h内第1份12导联心电图的Tp-Te间期,计算12导联平均Tp-Te间期,对测量结果分组、分导联进行比较分析.[结果]观察组12导联及12导联平均Tp-Te间期均较对照组显著延长(P 〈0.01).观察组内发生室性心律失常者较未发生室性心律失常者12导联Tp-Te间期明显延长,两组间比较除Ⅰ、aVL导联外均有显著性差异( P〈0.05);12导联平均Tp-Te间期比较有非常显著性差异( P 〈0.01).[结论]体表心电图Tp-Te间期能够反映AMI跨壁复极离散度的变化,AMI发生室性心律失常者较未发生室性心律失常者Tp-Te间期明显延长,Tp-Te间期有望成为预测AMI患者发生室性心律失常的临床指标.
