Abstract：Objective To compare the effect of three types of atrial fibrillation on left atrial size and to investigate the relationship between atrial fibrillation and left atrium. Methods Totally 78 patients of paroxysmal atrial fibrillation, 48 patients of persistent atrial fibrillation and 22 patients with permanent atrial fibrillation were analyzed by echocardiography. Left atrial end systolic diameter and Left ventricular ejection fraction were measured.Results Of the three groups of patients, the largest left atrial dimension was found in and the left atrial dimension in group of paroxysmal atrial fibrillation was the lowest ( P ＜ 0.05 ). Meanwhile the Left ventricular ejection fraction was the highest in the group of permanent atrial fibrillation(P ＜0.05). Conclusions Atrial fibrillation is one of the causes of left atrial enlargement. The longer the duration of atrial fibrillation is, the more significant enlargement left atrium showes.
