      are thoughtful. Limited data are available for patients with right bundle branch block (RBBB) and intraventricular conduction delay (IVCD). In our study of rescue left bundle branch area pacing (LBBAP), we only had 10 patients with RBBB (5%) and 28 patients with IVCD (14%).

      The cohorts are too small in this study to make any statement about the impact of IVCD on the treatment efficacy of LBBAP.
