中文摘要:
      目的:探讨P波离散度对心房颤动(房颤)导管消融术后复发的预测价值。方法:连续收集经导管消融的房颤患者120 例,根 据是否复发分为复发组与对照组,分别测定和比较两组术后心电图最大P波时限(Pmax)及最小P 波时限(Pmin)并计算P 波离散 度(Pd)。结果:房颤消融术后,53 例病人复发,复发组最大P波时限(132± 23mmVS 102± 25mm)及P 波离散度(33± 9mmVS 29± 10mm)均显著高于非复发组,差异有统计学意义(P<0.05)。结论:P波离散度可用于辅助预测房颤导管消融术后是否复发。
英文摘要:
      Objective:To investigate the relationship between successful pulmonary vein isolation and P-wave duration and search indexes for prediction atrial fibrillation recurrence.Methods:120 patients were treated with circumferential pulmonary vein isolation. After procedure, P-wave duration and P dispersion was studied on 12-lead surface electrocardiogram for each patient.Results:Atrial fibrillation recurrence was documented in 53 patients. The maximumP-wave duration(132± 23 mm VS102± 25 mm) and P dispersion(33± 9 mmVS 29± 10 mm) were significantly higher in the recurrence group than in without recurrence group.Conclusion:P-wave dispersion was a reliable index to predict the recurrence after pulmonary vein isolation.
