摘　　要：目的分析阵发性心房颤动(PAF)患者心电图P波的变化。方法选择100例无器质性心脏病阵发性房颤患者(PAF组),100例无房颤患者作为对照组(无PAF组),采用体表心电图和超声心动图分别测量两组的V1导联P波时限(Pt)、V1导联P波终末负电势(Ptfv1)和左心房内径(LAD)、舒张末期左心室内径(LVD)、左心室射血分数(LVEF)等指标。结果 PAF组、无PAF组的Pt分别为(120±10)ms、(99±11)ms,Ptfv1分别为(0.051±0.023)mm·s、(0.026±0.010)mm·s,两组比较差异有统计学意义(P均<0.01);PAF组、无PAF组LAD分别为(33.6±3.9)mm、(32.7±4.2)mm,LVD分别为(44.6±4.1)mm、(42.7±4.3mm),LVEF分别为(56.6±4.9)、(59.7±5.2),两组比较差异无统计学意义(P均>0.05)。结论阵发性房颤可引起心电图Pt及Ptfv1值增加,与左心房内径大小无相关。Objective To investigate the changes of electrocardiographic P wave in patients with paroxysmal atrial fibrillation.Methods Two hundred patients were divided into 2 groups： paroxysmal atrial fibrillation group（n = 100） as group PAF： patients with paroxysmal atrial fibrillation;control group（n = 100） as group no-PAF： patients with no atrial fibrillation.P wave duration,P terminal force in lead V1（Ptfv1）,left atrial diameter（LAD）,left ventricular diameter（LVD） and left ventricular ejection fraction（LVEF） were detected by electrocardiography and echocardiography.Results P wave duration was significantly longer in group PAF [（120 ± 10） ms,P ＆lt; 0.01] than in group no-PAF（99 ± 11） ms.Ptfv1 was greater in group PAF（0.051 ± 0.023） mm · s than in group no-PAF [（0.026 ±0.010） mm·s,P ＆lt;0.01].There were no diffenrences in the size of left atrium and ventricular between two groups（P ＆gt; 0.05）,the LVEF was also in the same level between two groups（P ＆gt; 0.05）.Conclusion Paroxysmal atrial fibrillation may induce the increased P wave duration and increase Ptfv1,which is independent of the size of left atrium.
