Article Abstract

Chronic right ventricular (RV) apical pacing may lead to the development of heart failure in some patients. Although pacing of the RV septum has been proposed as an alternative, positioning a lead in the true septum has proven challenging. In addition to fluoroscopy at implant, it has been suggested that 12-lead surface electrocardiogram (ECG) can be used to determine septal lead position; however, studies show this may be inaccurate. We present a case where a change in the ECG QRS axis late after pacemaker insertion with an active fixation lead highlights the difficulties of ECG localization of pacing leads.

Cardiac resynchronization therapy (CRT) improves outcomes in heart failure, but prior interventions like percutaneous mitral annuloplasty may hinder lead placement. We present a 70-year-old male with ischemic cardiomyopathy and severe functional mitral regurgitation who previously received a Carillon device. Due to coronary sinus inaccessibility, left bundle branch area pacing optimized cardiac resynchronization therapy (LOT-CRT) was performed.

Despite continued advancements in transcatheter aortic valve implantation (TAVI) techniques, the incidence of permanent pacemaker implantation (PPI) remains substantial. Established predictors of PPI include advanced age, pre-existing electrocardiographic conduction abnormalities, prosthetic valve type, implantation depth, and anatomical parameters, such as membranous septum length, which are currently under active investigation. In routine clinical practice, the management strategy often involves the temporary placement of a transvenous pacemaker lead, followed by a period of observation.

Background: During the electrode screwing process in left bundle branch pacing (LBBP), the significance of the S wave in lead V6 remains elusive. Our study analyzes the change of the S wave in lead V6 under different patterns of capture and explores its mechanisms.

Methods: This study included 243 cases with criterion of selective LBBP (SLBBP), we performed continuous pacing technique and classified the electrophysiological characteristics observed during the screwing process into four patterns: left ventricular septal pacing (LVSP), non-selective LBBP (NSLBBP) in low output and in the lower output, selective LBBP.
