Introduction and objectives: Left bundle branch area pacing (LBBAP), is a novel modality of physiologic pacing that requires an adequate assessment of the endocardium as well as the body-surface electrocardiographic signals for a successful pacing-lead implantation. The objective of the study consist of assessing if LBBAP criteria, specifically septal and left bundle branch pacing (LBBP) criteria, can be satisfactory measured using the signals resulting from different cardiac pacing analyzers (PSAs) by comparing them to the 'conventional' signals obtained from multichannel polygraph systems (MPSs) during the implantation procedure. Methods: Comparative observational, prospective, multicenter study between the signals obtained by PSA vs MPS of consecutive patients who underwent a LBBAP strategy as first intention.
