| 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±23mm VS 102±25mm）及P波离散度（33±9mm VS 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。

| Abstract: | 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 maximum P-wave duration（132±23 mm VS102±25 mm） and P dispersion（33±9 mm VS 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. |
