LBBAP 与 RVP 对房室传导阻滞患者新发房颤发生率的影响
左束支区起搏与右心室起搏对房室传导阻滞患者新发心房颤动发生率的影响:一项随机对照试验
This is a single-center, randomized controlled study. The aim of this study is to compare the impact of left bundle branch area pacing versus traditional right ventricular pacing on the incidence of atrial fibrillation in patients with atrioventricular block.

- Signed informed consent;
Exclusion Criteria:

- Patients with the history of atrial fibrillation;
- Having difficulties in follow-up: Those who cannot accept 2-year follow-up on time due to physical condition or other reasons;
- Pacemaker replacement without new implanted ventricular electrodes;
- Surgery is required within 1 year due to severe structural heart disease;
- Patients with tricuspid mechanical valve replacement, or congenital heart disease (including transposition of the great arteries, or permanent left superior vena cava, etc);

武器和干预
参与者组/臂 |
干预/治疗 |
|---|---|
|
实验性的:左束支区起搏
|
Left bundle branch area pacing(LBBAP) is a novel physiological pacing form for ventricular pacing. In patients received LBBAP, the pacing lead will be placed at left bundle branch area to achieve narrow paced QRS duration. |
|
有源比较器:右心室起搏
|
Right ventricular pacing is the traditional pacing modality for ventricular pacing. The pacing lead was placed in the apex or septum of right ventricle. |
