WebTherefore, more recently left bundle branch pacing (LBBP) has been introduced to correct left bundle branch block. LBBP seems to be possible in a wider anatomic area and may be easier to implant. However, LBBP requires active screw-in of the lead deep into the ventricular septum. WebMar 12, 2024 · The specialized AV conduction system consists of the AV node (AVN), the "His bundle," and the right and left bundle branches (RBB and LBB). The AV node conducts the electrical impulse to the His bundle. 7 The His bundle passes the signal to the right and left bundle branches.
