Bachmann bundle versus right atrial appendage pacing in sick sinus syndrome

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This single-center prospective observational cohort will compare patients with sick sinus syndrome who receive Bachmann bundle pacing versus conventional right atrial appendage pacing during de novo permanent pacemaker or ICD implantation. Participants will undergo baseline and serial echocardiography including left atrial size and left atrial strain measurements, with clinical follow-up to capture arrhythmias and other outcomes. Investigators will compare progression of atrial cardiomyopathy by analyzing changes in structural and functional atrial parameters and clinical event rates between the two pacing-site groups. The goal is to see whether improved interatrial conduction with Bachmann bundle pacing leads to less atrial remodeling and better clinical outcomes over time.
