摘　　要：目的:研究QTc离散度在急性冠脉综合征介入治疗中的变化及临床意义。方法:测量42例成功进行单支或多支PCI治疗患者术前及术后24h十二导联同步心电图的QTcd,并与对照组进行比较。结果:治疗组治疗前后QTcd分别为(61.15±6.84)ms和(40.57±6.08)ms,差异有统计学意义(P<0.01)。对照组QTcd为(61.26±6.77)ms和(60.92±6.93)ms,差异无统计学意义(P>0.05)。结论:成功的PCI治疗能显著降低急性冠脉综合征患者的QTcd,可减少恶性心律失常的发生,从而改善急性冠脉综合征患者的预后。Objective： To research the changes and clinical significance of QTc dispersion in patients with acute coronary syndrome intervention. Methods： Measurement of 42 cases of successful single or multi-branch PCI patients were treated with preoperative and postoperative 24-hour 12-lead ECG synchronization QTcd and compared with the control group. Results： It was remarkably different for PCI group that QTc dispersion before and after PCI treatment were （61.15±6.84） ms and （40.57±6.08） ms respectively （P〈0.01）, it showed unapparent difference for control group that QTc dispersion were （61.26±6.77） ms and （60.92±6.93） ms respectively （P〉0.05）. Conclusion： Successfully PCI treatment can evidently reduce QT dispersion and reduce arrhythmia risk in patients with ACS, thus improve anticipation.
