Measurements during LBBAP. A Baseline and RVa-paced QRS durations were 172 ms and 191 ms, respectively. B After bipolar LBBAP, LVAT was 71 ms, Bipolar stim to QRS duration was 136 ms, and LBB-paced QRS duration was 110 ms. Non-selective LBBAP was achieved. LBB left bundle branch, LBBAP left bundle branch area pacing, LVAT left ventricular activation time, RVa right ventricular apex
