Study of Heart Electrical Activity with Left Bundle Branch Area Pacing in Adults Investigating Heart Signal Patterns in Patients with Pacemakers Using LBBAP

What this Trial Is About

Researchers are investigating the electrical features of the heart during different pacing outputs and body positions in left bundle branch area pacing LBBAP. This study aims to help develop and validate a new algorithm to better identify left bundle branch LBB capture during LBBAP, which may improve understanding of heart pacing effects. The study focuses on patients with heart failure or bradycardia who have received LBBAP therapy. The study observes patients who have had LBBAP therapy for 1 to 4 months and have devices capable of providing real-time intracardiac electrograms. There is no active treatment or intervention involved. The study monitors electrical characteristics under various pacing outputs and body positions, aiming to differentiate between LBB capture and left ventricular septal pacing LVSP. Participants will be followed from 1 month up to 4 months after receiving LBBAP therapy, with an optional follow-up at 6 months after enrollment. During this time, researchers will collect data on intracardiac electrical signals and their correlation with ECG findings. No additional treatments are given the study focuses on collecting and analyzing heart electrical activity to understand pacing effects and improve pacing methods.
