P波离散度对房颤消融术后复发的预测价值

Predictive Value of P-wave Dispersion Degree on the Postoperative Pecurrence of Atrial Fibrillation

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。

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.
