目的 :探讨校正QT间期离散度 (QTcd)在急性心肌梗死 (AMI)溶栓治疗后判断梗死相关血管再通及预测恶性室性心律失常 (MVA)发生的价值。方法 :选择分析AMI患者 46例 (全经溶栓治疗及冠脉造影 ) ,分再通组及未通组 ,恶性室性心律失常发生组 (MVA)和恶性室性心律失常未发生组 (NMVA) ;并对入院时及入院后 2 4h的QTcd进行分析对比 ,且在入院后行心电监护一周 ,观察MVA的发生情况。结果 :再通组和未通组患者的QTcd比较有显著差异 ;MVA组与NMVA组患者的QTcd比较亦有显著差异。结论 :溶栓后 2 4h内QTcd明显下降可作为AMI溶栓后梗死相关血管再通的无创指标之一 ,并预示AMI后早期MVA发生率减少。
Objective: To investigate the value of corrected QT dispersion (QTcd) in predicting infarct related vascular recanalization and predicting the occurrence of malignant ventricular arrhythmias after acute myocardial infarction (AMI) thrombolysis. Methods: Forty-six cases of AMI (total thrombolysis and coronary angiography), sub-recanalization group and failure group, MVA group and NMVA group ). The QTcd at admission and at 24 hours after admission were analyzed and compared, and the electrocardiogram (ECG) monitoring was performed for one week after admission to observe the occurrence of MVA. Results: There were significant differences in QTcd between recanalization group and non-recanalization group. There was also significant difference in QTcd between MVA group and NMVA group. Conclusion: The significant decrease of QTcd within 24 hours after thrombolytic therapy may be one of the noninvasive indicators of infarct-related revascularization after AMI thrombolysis, which indicates the decrease of early MVA incidence after AMI.
