Official title
The Pacing in Atrioventricular Block: a Comparative Evaluation of Central Haemodynamics, Cardiac Function, and Quality of Life
Overview
A randomized, single-blind study comparing two pacing strategies in patients with atrioventricular block requiring permanent pacemaker implantation. This trial evaluates the impact of conduction system pacing (left bundle branch area pacing) versus standard right ventricular pacing on central hemodynamics, cardiac function, and patient quality of life over 12 months. The study will enroll 124 patients from two Estonian tertiary hospitals and measure central systolic arterial pressure as the primary outcome, with secondary assessments of arterial stiffness, echocardiographic parameters, electrical activation patterns, and quality of life scores.
Interventions
- Device Right ventricular pacing
Pacemaker implantation with RV lead placement - Device Conduction system pacing
Pacemaker implantation with conduction system (LBBAP) lead placement
Primary outcome measures
- Central systolic blood pressure [Time frame: One year post implantation of pacemaker]
