摘　　要：目的分析房颤患者的心电图f波特点与左房内径,为解释房颤维持机制提供临床参考依据。方法收集2008年1月至2011年1月我院住院的房颤患者共391例,从持续性房颤患者中随机抽取50例,从阵发性房颤患者中随机抽取50例,测量每例病例的心电图V1导联f波振幅、时限,f-f间期、左房内径等指标,对两组结果进行统计学分析。结果持续性房颤组的f波振幅、f波时限、f-f间期小于阵发性房颤组,而左房内径大于阵发性房颤组,其差异有统计学意义(P<0.05)。结左房内径增大、心房不应期缩短可能是持续性房颤的病理机制。Objective To Provide clinical references for explaining atrial fibrillation maintaining mechanism, by analyzing the f wave and left atrial inner dimension in patients with atrial fibrillation. Methods A total of 391 cases of atrial fibrillation was collected from January 2008 to January 2011 in our hospital, then 50 cases were selected randomly from chronic atrial fibrillation and 50 cases from paroxysmal atrial fibrillation. The amplitude of f wave, timing, f-f interval and left atrial dimension, and so on, were measured, then made a statistics analysis of the results. Results The index above in the Paroxysmal atrial fibrillation group are lower than that of the persistent atrial fibrillation, except inner diameter. There were statistic differences between the two groups （P 〈 0.05）. Conclusion The increase of left atrial dimension, the shorten of refractory period of atrium maybe the pathological mechanism of atrial fibrillation.
