Electroanatomic mapping of the right atrial breakout site during retrograde Bachmann bundle pacing in 15 patients in sinus rhythm undergoing pulmonary vein isolation provided the anatomic localization of the putative lead insertion target for Bachmann bundle pacing. In all patients the target area could be mapped to the inferoseptal superior vena cava, with some variation in the earliest breakout site in the anteroposterior plane. Microstructural correlation reveals that the Bachmann bundle functions as an atrial conduction pathway supported by anatomic features to provide interatrial synchrony.
在15例接受肺静脉隔离的窦性心律患者中，进行逆行巴赫曼束起搏时对右心房突破位点进行电解剖标测，确定了巴赫曼束起搏假定的导线插入靶点的解剖定位。在所有患者中，目标区域可标测到下间隔上腔静脉，前后平面最早突破位点存在一定差异。微观结构相关性研究表明，巴赫曼束作为一条心房传导通路，由解剖学特征支持，以实现心房同步。
