Clinical trial Recruiting at 2 sites Interventional Ages 18 to 65

Comparing cardioneuroablation and permanent pacing for treating bradycardia symptoms.

Official title: A Multicenter, Randomized, Double-blind, Research Study comparinG the Efficacy and Safety of cardioneuroablaTion vs Permanent Pacing in Patients With an implantabLE PACEmaker for Symptomatic Bradycardia.

Run by 4th Military Clinical Hospital with Polyclinic, Poland · NCT05896592 · Data updated 2026-11-12

This study is testing if a new treatment called cardioneuroablation can help people with slow heart rates feel better and possibly stop using their pacemakers.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-65 who have undergone pacemaker implantation for sinus node or atrioventricular node dysfunction and have a positive response to the atropine test.

Probably not a fit

Patients with severe bradycardia, certain heart conditions, or those outside the age range may not benefit from this study.

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

What this trial studies

This clinical trial evaluates the efficacy and safety of cardioneuroablation (CNA) as an alternative to permanent pacemaker (PM) therapy in patients suffering from symptomatic bradycardia due to sinus node dysfunction or atrioventricular block. Participants will be randomized into groups receiving either CNA or continued PM therapy, with assessments including ECG monitoring, symptom history, and device checks over several months. The study aims to determine if CNA can effectively alleviate symptoms and allow for the discontinuation of PM therapy, potentially improving patient quality of life.

Why it matters

Potential benefit: If successful, this approach could provide patients with a non-invasive option to manage bradycardia symptoms and reduce reliance on permanent pacemakers.

How similar studies have gone: While the use of cardioneuroablation is gaining attention, this specific comparison with permanent pacing is relatively novel and has not been extensively tested in prior studies.
