Comparison of electrocardiographic parameters between left bundle optimized cardiac resynchronization therapy (LOT ‐CRT) and left bundle branch pacing—cardiac resynchronization therapy (LBBP‐CRT)

ConclusionsIn patients with NICMP and LBBB, there was no significant difference in QRSd with LOT-CRT compared to LBBP-CRT. However, in patients with QRSd  >  131 ms after LBBP-CRT, LOT-CRT resulted in a significantly narrower QRS.
