“…proposed criteria of LBBB, which is now widely used to screen CRT candidates, including QRSd ≥140 ms for males or ≥130 ms for females, QS or rS wave in leads V1 and V2 and mid‐QRS notching or slurring in ≥2 of leads V1, V2, V5, V6, I, and avL. Several studies have confirmed LBBB morphology meeting Strauss criteria was a strong predictor of echocardiographic response and favorable outcome following CRT 6,7 . Thus, LBBB meeting Strauss criteria is considered as true LBBB while LBBB not meeting Strauss is deemed as false LBBB or NICD with LBBB‐like morphology.…”

The efficacy of cardiac resynchronization therapy (CRT) in heart failure patients with left bundle branch block (LBBB) is well established with Class I or IIa recommendation according to 2021 ESC Guidelines on cardiac pacing and CRT, whereas non‐LBBB morphology is less recommended. There is insufficient evidence that proves patients with NICD could benefit from CRT. As patients with NICD are characterized by heterogeneity, the effect of CRT on these patients is still controversial. Although the proportion of NICD in the population is lower than that of LBBB patients, it is still worth investigating the effects of CRT on patients with NICD in an era of His‐Purkinje conduction system pacing (HPCSP).

“…Left ventricular activation during trueLBBB can be reproduced by pre-existing the right ventricular (RV) septum with RV septal pacing (RVSP). On the other hand, RV septal pacing in patients with IVCD leads to additional trans-septal conduction delay, which is not present during the spontaneous rhythm [ 3 ].…”
