结论左心房增大与心房颤动有密切关系。
Conclusion The left atrium enlargement is related to atrial fibrillation.
甲减时，心率减慢、左心房增大、左心室心肌重量增高和短轴缩短率降低。
Slow heart rate, enlarged left atrium, increased left ventricular mass and decreased fractional shortening were detected in patients with hypothyroidism.
结果：与窦性心律组相比，心房颤动患者组左心房内径明显增大。
Results: Compared with SR group, Left atrial inner diameter was significantly increased in the patients of the AF group.
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。
Conclusion the increase of left atrial dimension, the shorten of refractory period of atrium maybe the pathological mechanism of atrial fibrillation.
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。
