Left bundle branch area pacing (LBBAP) has recently been introduced as a physiological technique with synchronous left ventricular activation. It was our aim to evaluate the feasibility and learning curve of technique, well electrical characteristics LBBAP.LBBAP attempted in 80 consecutive patients electrocardiographic were evaluated during intrinsic rhythm, right septum (RVSP) LBBAP. Permanent lead implantation successful 77 (96%). LBBAP time fluoroscopy shortened significantly from 33 ± 16 21 13 min 17 5 12 7 min, respectively, first 20 last patients. (LBB) capture achieved 54 (68%). In 36 45 (80%) intact atrioventricular conduction narrow QRS, an LBB potential (LBBpot) present LBBpot onset QRS interval 22 6 ms. duration increased more RVSP (141 ms) than (125 19 ms), compared 130 30 ms without pacing. An even clearer difference observed for area, which (from 32 µVs 73 µVs) (41 15 µVs). smaller (43 18 vs µVs, respectively). (n = 54), stimulus R‑wave peak V6 shorter (75 14 88 9 ms, respectively).LBBAP is safe feasible clear that seems flatten after 40-60 implantations. two-thirds Compared RVSP, largely maintains synchrony at level close (narrow QRS) rhythm.
