　　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 ven-tricular diameter(LVD) and left ventricular ejection fraction(LVEF) were detected by electrocardiography and echo-cardiography .Results P wave duration was significantly longer in group PAF [ ( 120 ±10 ) ms, P<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<0.01].There were no diffenrences in the size of left atrium and ventricular between two groups(P>0.05), the LVEF was also in the same level between two groups (P>0.05).Conclusion Paroxys-mal atrial fibrillation may induce the increased P wave duration and increase Ptfv 1, which is independent of the size of left atrium.
