溶栓对急性心肌梗塞QTc离散度的影响

Effect of thrombolytion on QTc dispersion in AMI

目的探讨溶栓对急性心肌梗塞(AMI)QTc离散度(QTcd)的影响。方法选择42例接受静脉溶栓治疗AMI患者,其中28例溶栓成功。分别测量溶栓成功组和失败组溶栓前后的QTcd。结果溶栓成功组溶栓后QTcd较溶栓前显著缩短[(89.9±23.2)msvs(60.5±13.6)ms,P<0.05]。溶栓失败组QTcd保持较高水平[(85.6±28.2)msvs(98.6±20.1)ms]。结论溶栓治疗成功可使AMI后的QTcd显著降低。

Objective To evluate the effets of thrombolytion on QTc dispersion in AMI. Methods 42 acute myocardial infartion patients were studied, and 28 of which were succeeded in thrombolytion. QTcd was measured after entering the hospital and three days later. Results The QTcd was significantly reduced in grade with successful thrombolytion from (89.97±23.2)ms to (60.5±13.6)ms, P<0.05].QTcd remained long in grade without successful thrombolytionfrom (85.6±28.2)ms to(98.6±20.1ms)].Conculsions Successful thrombolytion can reduce QTcd in AMI.
