摘　　要：[目的]观察扩张型心肌病患者及扩心病合并有阵发性房颤患者P波离散度(pdisp,Pd)、P波最大时限(Pmax)对扩心病患者合并阵发性房颤发生的预测价值。[方法]选择扩张型心肌病患者112例,按有无房颤分为两组:I组为扩心病合并有阵发性房颤病史的患者;Ⅱ组为单纯原发性扩心病和继发性扩心病患者,测量各组的Pd及Pmax,评估其对扩心病患者合并阵发性房颤的发生的预测价值。[结果]I组与II组Pd和Pmax增大(45.3±12.7、121.5±16.3、24.7±10.5、107.3±10.3),两组相比差异有显著性意义(P<0.05);Ⅰ组Pd明显增大,Pmax持续时间、Pd与LAD大小呈正相关,即随着心房的扩大,Pmax在Ⅰ组明显>Ⅱ组(P<0.05)。[结论]Pd作为房颤的心电图预测指标,具有无创、简便、比较可靠的特点,可作为预测扩张型心肌病合并阵发性房颤的预测指标。[Objective]To investigate the P wave dispersion(Pdis) and maximum P wave duration(Pmax) in prediction of paroxysmal atrial fibrillation(PAF) in patients with dilated cardiomyopathy.[Methods] One hundred and twelve patients with dilated cardiomyopathy were included in this study,which were divided into group with(Group I) and without PAF(Group II).The Pdis and maximum P wave were measured in each group,and their co-relationship with PAF was analyzed.[Results] The Pdis and Pmax in Group II(45.3±12.7 and 24.7±...
