| ［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。 |

| ［Abstract］ 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<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 Paroxysmal atrial fibrillation may induce the increased P wave duration and increase Ptfv1, which is independent of the size of left atrium. |
