右室心尖起搏可引起左右心室收缩同步,可能造成心功能的减退。而持续希氏束旁起搏可能保留心室间的同步性并改善左心室功能。本研究的目的是评估慢性心房颤动(房颤)伴窄QRS波患者房室结消融后持续希氏束旁起搏方式的可行性与安全性及其对血流动力学的改善作用。方法:入选患者为
Right atrial apical pacing can cause systolic left ventricular systole, may result in decreased cardiac function. Continued His bundle pacing may preserve interventricular systolic and improve left ventricular function. The purpose of this study was to evaluate the feasibility and safety of continuous pacing and subsequent improvement of hemodynamics following atrioventricular node ablation in patients with chronic atrial fibrillation (atrial fibrillation) and narrow QRS. Method: selected patients
