摘　　要：目的探讨心电图P波参数对阵发性房颤患者导管消融术后复发的评估价值。方法抽取2020年1月至2021年5月滨州市中心医院收治的84例阵发性房颤患者作为观察组,同期于医院体检的非阵发性房颤患者60例作为对照组。所有患者均行心电图检查,比较两组心电图P波参数变化。观察组患者采用导管消融术治疗,术后随访1年,依据是否复发分为复发组与未复发组,收集两组患者术前P波参数,绘制受试者工作特征曲线分析最大P波时限(Pmax)、P波离散度(Pd)、V1导联P波终末电势(PtfV1)及联合检测在预测阵发性房颤患者复发中的应用价值。结果观察组Pmax、Pd、PtfV1高于对照组,差异有统计学意义(P<0.05);84例阵发性房颤患者随访1年,复发24例,复发率为28.57%(24/84);复发组术前Pmax、Pd、PtfV1高于未复发组,差异有统计学意义(P<0.05);绘制受试者工作特征曲线结果显示,Pmax、Pd、PtfV1及联合检测预测阵发性房颤患者复发的曲线下面积分别为0.727、0.757、0.642、0.954,联合检测的预测价值最高。结论阵发性房颤患者发病后心电图P波参数可发生明显变化,联合检测心电图P波参数能够进一步提高复发预测的准确性,便于临床完善早期治疗方案。Objective To investigate the value of electrocardiogram(ECG)P wave parameters in prediction on the recurrence of paroxysmal atrial fibrillation after catheter ablation.Methods Eighty-four patients with paroxysmal atrial fibrillation treated in Binzhou Central Hospital from January 2020 to May 2021 were selected as the observation group,and 60 patients with non paroxysmal atrial fibrillation who underwent physical examination in the hospital were selected as the control group.All selected patients underwent ECG examination,and the changes of ECG P wave parameters were compared between the two groups.Patients in the observation group were treated by catheter ablation,and they were followed up for 1 year.Moreover,they were further divided into recurrent group and non recurrent group according to recurrence of paroxysmal atrial fibrillation.The preoperative P-wave parameters of the recurrent group amd non recurrent group were collected.The receiver operator characteristic curve was drawn to analyze the clinical value of maximum P wave duration(Pmax),P wave dispersion(Pd),lead V1 P wave terminal potential(PtfV1)and combination of them in predicting the recurrence of paroxysmal atrial fibrillation.Results Pmax,Pd and PtfV1 in the observation group were significantly higher than those in the control group correspondingly(P<0.05);84 patients with paroxysmal atrial fibrillation were followed up for 1 year,of which 24 cases had recurrence,and the recurrence rate was 28.57%(24/84).The preoperative Pmax,Pd and PtfV1 in the recurrent group were significantly higher than those in the non recurrent group(P<0.05).The results of the receiver operator characteristic curve analysis showed that the area under the curve of Pmax,Pd,PtfV1 and combination of them in prediction on the recurrence of patients with paroxysmal atrial fibrillation were 0.727,0.757,0.642 and 0.954,respectively,and the predictive value of combination of these indexes was the highest.Conclusions The P wave parameters of ECG can change significantly after the ons
