大型研究表明双腔起搏在改善生活质量、降低心衰住院率及房颤发生率方面优于心室起搏,但在改善生存率及减少脑卒中方面前者无优势;还有小型研究显示心房起搏优于心室起搏及双腔起搏。对于窦房结功能障碍而房室结功能正常且无束支传导阻滞的患者推荐植入单腔心房起搏器。
Large studies have shown that dual-chamber pacing is superior to ventricular pacing in improving quality of life, reducing hospitalization for heart failure and the incidence of atrial fibrillation, but there is no advantage in improving survival and reducing stroke; and small studies have shown that atrial Stroke is superior to ventricular pacing and double-chamber pacing. For sinus node dysfunction and atrioventricular nodal function is normal and no bundle branch block patients recommended implantation of single-chamber atrial pacemaker.
