摘要 分别测量65例STEMI患者(观察组)和65例健康者(对照组)的心电图QT离散度(QTd)和T波峰末间期(Tp ̄e),对比分析两组Tp ̄e/QT比值及观察组恶性室性心律失常者与Tp ̄e/QT比值的关系。结果观察组QTd、Tp ̄e均明显延长,Tp ̄e/QT比值明显高于对照组,组间比较具有统计学意义(P<0.05);观察组发生恶性室性心律失常者19例(29.2%)作为恶性室性心律失常组,其Tp ̄e/QT比值明显高于无恶性室性心律失常组,组间比较差异具有统计学意义(P<0.05)。心电图Tp ̄e/QT比值监测,对预测STEMI患者恶性室性心律失常有重要的临床价值,可作为SCD重要的预警指标之一。
