Central Haemodynamics and Pacing for AV Block

In plain words

What the trial is, and whether it could suit you

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.
