摘要 目的 :探讨冠状动脉介入手术 (PTCA和冠状动脉内支架置入术 )对冠心病患者QT离散度 (QTd)的影响。方法 :记录 6 1例冠心病患者介入手术前后静态 12导联心电图 ,计算QTd ,并进行对比分析。结果 :6 1例冠心病患者介入性治疗前QTd为 (10 5 7± 41 3)ms ,介入性治疗后QTd为 (5 9 4± 2 8 6 )ms,前后相比QTd差异有显著性 (P <0 0 1)。PTCA术后与冠脉内支架置入术后QTd分别为 (6 2 9± 2 9 2 )ms和 (5 6 2± 2 8 1)ms,二者相比差异无显著性(P >0 0 5 )。结论 :冠心病经介入性治疗后QTd明显减小 ,QTd可作为介入手术后心肌再灌注成功的参考指标。是否可作为冠脉再狭窄的早期指标 。
