急性心肌梗塞急诊溶栓后QT离散度的研究

A CLINICAL STUDY ON QT DISPERSION OF THE PATIENTS WITH ACUTE MYOCARDIAL INFARCTION AFTER VENOTHROMBOLYSIS

观察 5 8例急性心肌梗塞静脉溶栓后再通组与未再通组 QT离散度 ( QTd)的变化及对比 ,并探讨其临床意义。选取医院近 2年内在急诊科确诊心肌梗塞并行静脉溶栓治疗病人 5 8例 ,记录溶栓前后同步标准体表 1 2导联心电图 ,测算 QTd。再通组与未再通组 QTd相比显著减小 ( P<0 .0 1 )。溶栓再通后 QTd较溶栓显著减小。QTd可以作为溶栓再通临床观察指标之一。

To constrast QT disperison( QTd) of the recanalized palients with( acute myocardial infarction,AMI) with that of the unrecanalized ones and to investigate the clinical signficance,venothrombolysis was performed in 5 8proven patinets with AMI. Before and after the venothrombolysis,1 2 - lead ECG was recorded and QTd was analysed. The QTd of the recanalized group declined signifieantly in comparison with that of the unrecanalized one ( P<0 .0 1 ) in all of the patients with AMI remaining in the emergency rooms for 2 years. The venothrombolysis could effectively have the embolized vessels recanzlized and the myocardia reperfused. There was amarked QTd difference between prevenothrombolysis and postvenothrombolysis. The QTd of the recanalized group decreased more notably than that of the unrecanalized one.The results showed that QTd could be considered as an indication of clinical observation.
