目的：观察老年特发性心房颤动(简称房颤)和复律后心脏功能的改变。方法：采用彩色多普勒二维超声心动图仪测定老年人持续、阵发性房颤及房颤复律后左心功能的各项指标，并与健康老年人进行对照。结果：(1)射血分数、每搏量、心输出量、心脏指数及左心房内径各指标：持续、阵发性房颤组及房颤复律组与正常对照组比较，依次为差异非常显著(P<0.01)；差异显著(P<0.05)及差异不显著(P>0.05)；(2)房颤复律组E/A为0.71±0.14，与照对组比较差异非常显著(P<0.01)；(3)持续、阵发房颤组的各项心功能指标与房颤复律组比较，分别为P<0.01，P<0.05。结论：老年特发性持续房颤患者存在明显左心功能障碍；阵发性房颤者短时间内可出现左心功能改变；房颤复律后心脏收缩功能可恢复或接近正常，但仍存在不同程度舒张功能障碍。

Objective:To observe the changes of cardiac function in elderly idiopathic patient s with atrial fibrillation(AF) and after cardioversion. Methods: The various left ventricular function indexes of elderly idiopathic patients wi th persisten t AF (groupⅠ),paroxysmal AF (groupⅡ),and after cardioversion (group Ⅲ) were d etermined by two dimensional and doppler color echocardiogram,compared with nor mal elders(control group). Results:The various indexes includes EF、SV、CO、CI and LA diameter of group Ⅰ、Ⅱ、Ⅲ,compared with its of control group ,respectively very significant difference (P<0.01)、sig nificant difference (P<0.05)、no difference.The E/A ratio of group Ⅲ had a significant difference compared with its of control group (P<0.01) .Compared with group Ⅲ，the various indexes in group Ⅰ and group Ⅱ，had a sig nificant difference(P<0.01,P<0.05) respectively.Conclusion: The cardiac function of elderly idiopathic patients with persistent AF decreases,its of paroxysmal AF shortly decreases；the systolic function may returns to normal,but diastolic function still decreases after cardioversion.
