目的用二维超声研究正常人左心房内径、容量。
Objective To observe normal citizen's LA's internal diameter and volume by two dimensional echocardiography.
阵发性房颤组左心房内径与对照组相比差异无统计学意义。
But the difference of LAD between the paroxysmal atrial fibrillation group and the control group was not statistically significant.
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.
同时应用心脏超声测量各组病人左心房内径以及左心室射血分数。
Left atrial diameter (LAD) and ejection fraction (ef) of each group were measured by echocardiography respectively.
目的：探讨辛伐他汀对心房颤动患者左房内径(LAD)的影响。
Objective: To explore the effect of simvastatin on the left atrial dimension (LAD) of patients with 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。
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。
