经冠状窦内消融治疗左房消融治疗心房颤动术后患者的典型心房扑动和房性心律失常。
Catheter ablation of atypical atrial flutter and atrial tachycardia within the coronary sinus after left atrial ablation for atrial fibrillation.
高血压患者有较高心律失常的发生率，房性心律失常可能与左房扩大或心房纤维化有关。
Hypertensive patients have a higher incidence of atrial arrhythmia which might be related to atrial enlargement or fibrosis.
射频消融左心房后壁后，刺激诱发的房性心律失常有减少趋势，提示左心房后壁可能存在房性心律失常发生的基质。
The atrial arrhythmia induced by extra stimulus has a tendency of decrease after ablation may suggests that there is substrate related to arrhythmias in left atrium.
在19个月的平均随访期内，14名患者(56%)继续保持稳定的窦性心律，而11名患者(44%)出现阵发性AF、永久性AF或左心房房速复发。
During a mean follow-up of 19 months, 14 patients (56%) remained in stable sinus rhythm, and 11 patients (44%) experienced recurrence of paroxysmal AF, permanent AF, or left atrial tachycardia.
目的研究高血压病患者左心房重构对房性心律失常的影响。
Objective to investigate the effects of left atrial enlargement on atrial arrhythmias in hypertensive patients diagnosed according to WHOs standard.
方法：窦性心律下，标测左心房和左上肺静脉的电位。
Methods the left atrial, left superior pulmonary veins were mapped in the sinus rhythm.
结果窦性心律时窦房结发出冲动，激动右心房上部并向右心房下部和左心房传导，而房颤时双心房均可见方向不一、片段的激动波或大的折返环，可见多个传导阻滞区。
During acute AF, there are multiple and discrete excitation wave fronts or reentry activities were found in both LA and RA, and bidirectional block regions could be shown.
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。
