A step forward toward conduction system pacing –based cardiac resynchronization therapy, albeit a small one

Starting from the very first clinical reports of the deep septal pacing technique by Mafi-Rad and coworkers1 and Huang and coworkers,2 it became clear that the activation of the left ventricle (LV) during pacing near the left conduction system —the method known as left bundle branch area pacing (LBBAP)—results in paced QRS that in contrast to the conventional right ventricular pacing technique has none of the features of left bundle branch block (LBBB). On the contrary, the reported LBBAP paced QRS complexes showed rapid activation ov er the LV and demonstrated right bundle branch block pattern.
