Background: Left bundle branch area pacing (LBBAP) has gained increased adoption globally with the use of both lumenless leads (LLLs) and stylet-driven leads (SDLs). As these leads have been developed for conventional endocardial pacing sites, concerns remain regarding the lead integrity with LBBAP.
Objectives: This study evaluates lead integrity of pacing leads used for LBBAP in a large, real-world cohort of patients with LBBAP.

Background: Continuous deep septal pacing and signal recording during implantation of left bundle branch pacing (LBBP) lead enables to monitor beat-to-beat changes of electrocardiogram (ECG) and myocardial current of injury (COI) as the lead crosses the septum.
Objectives: This study aimed to characterize patterns of continuous QRS, ST-T, and COI change for monitoring of the lead depth and instantaneous determination of the obtained capture type (LBBP vs left ventricular septal pacing [LVSP]).
Methods: The ECG and COI during lead implantation were scrutinized for sudden changes of V R-wave peak time, V initial and terminal R-wave amplitude, V-V R-wave amplitude, repolarization pattern and S-wave amplitude in I, V-V, and COI drop.
Heart rhythm management is a continuously evolving sub-speciality of cardiology. Every year, many physicians and allied professionals (APs) start and complete their training in cardiac implantable electronic devices (CIEDs) or electrophysiology (EP) across the European Heart Rhythm Association (EHRA) member countries. While this training ideally ends with an EHRA certification, the description of the learning pathway (what, how, when, and where) through an EHRA core curriculum is also a prerequisite for a successful training.

Implantation was successful and safe in 11 of 12 patients, with adequate defibrillation testing, good electrical and electrocardiographic parameters, and uneventful device-related short-term follow-up.
