摘要
目的探讨PCI治疗对急性冠脉综合征患者QTc离散度的影响。方法对照分析20例成功进行单支或多支PCI治疗患者术前及术后24h心电图与同期未行PCI治疗的20例急性冠脉综合征患者入院时及24h后12导联心电图对比分析,测量QTcd。结果PCI组治疗前后QTcd分别为62.25±7.15ms和44.75±6.12ms,差异有非常显著性意义。对照组QTcd为63.50±7.05ms和63.15±6.12ms,差异无显著性意义。结论有效PCI治疗能显著降低急性冠脉综合征患者的QTcd,降低心律失常的危险度,从而改善急性冠脉综合征患者的预后。
Objective To determine whether PCI treatment influence QTcd dispersion in patients with ACS. Methods Standard 12-tead electrocardiograms recorded before and 24h after PCI in 20 patients with ACS successfully treated , comparing with the others recorded on and 24h after admission in 20 patients with ACS with undo PCI treatment in the corresponding period. Results It was remarkable difference for PCI group that QTc dispersion before and after PCI treatment were 62.25±7.15ms and 44.75±6.12ms,it was inapparent difference for comparing group that QTc dispersion were 63.50±7.05ms and 63.15± 6.12ms. Conclusion Effective PCI treatment could evidently reduce QT dispersion and reduce arrhythmia risk in patients with ACS, thus improving anticipation.
