摘　　要：目的探讨心房纤颤(房颤)的类型与左心房增大的关系。方法选择100例房颤患者,按临床发生房颤的持续时间分类,<7d者为阵发性房颤(30例),≥7d者为持续性房颤(70例)。患者均行超声心动图检查,测定左心房内径、左心室舒张末内径及左心室射血分数(EF)。结果阵发性房颤患者左心房内径、左心室舒张末内径及左心室EF分别为(36.5±4.5)mm、(47.4±5.2)mm和(57.2±7.1)%,持续性房颤患者分别为(44.8±6.0)mm、(51.2±5.4)mm和(44.6±0.6)%,两组患者左心房内径及左心室舒张末内径间差异有统计学意义(P<0.05)。结论持续性房颤患者左心房内径及左心室舒张末内径显著大于阵发性房颤者,可见房颤的类型与左心房的大小有关。Objective To study the relationship between left atrial size and atrial fibrillation. Methods Totally 100 patients with atrial fibrillation, according to the duration of clinical atrial fibrillation, were classified as paroxysmal atrial fibrillation group （n=30, the duration〈7 days） and persistent atrial fibrillation （n=70, the duration ≥7 days. The parameters of left atrial diameter （LAD）, left ventricular end diastolic diameter （VDD） and left ventricular ejection fraction （LVEF） were measured in both groups by echocardiography. Results The values of LAD, VDD and LVEF were respectively （ 36.5 ± 4.5 ） ram, （ 47.4 ± 5.2 ） mm and （ 57.2 ± 7.1 ） % in patients with paroxysmal atrial fibrillation, and （ 44.8 ± 6.0 ） mm, （ 51.2 ± 5.4 ）mm and （ 44.6 ± 0.6 ） % in patients with persistent atrial fibrillation, with significant differences in LAD and VDD between the two （ P〈0.05 ） . Conclusion LAD and VDD are remarkably larger in patients with paroxysmal atrial fibrillation than in patients with persistent arterial fibrillation, so left atrial size is related with type of atrial fibrillation.
