Evaluating long-term outcomes of conduction system pacing

Official title: Long-term Outcomes of Conduction System Pacing: a National Multicenter Observational Study - NORMAND'HIS / STIMU'HIS

Run by University Hospital, Rouen · NCT06088927 · Data updated 2026-11-12

This study is testing how well conduction system pacing works over two years for people with heart issues by looking at their heart function and any episodes of atrial fibrillation.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults over 18 years old who have undergone a conduction system pacing attempt.

Probably not a fit

Patients who are under guardianship, pregnant, breastfeeding, or lack effective contraception may not benefit from this study.

What this trial studies

This prospective multicenter registry aims to assess the long-term electrical, echocardiographic, and clinical outcomes of conduction system pacing (CSP). The study will collect data on pacing thresholds, impedance, and R wave sensing during follow-up visits to evaluate the stability of CSP over a two-year period. Additionally, it will monitor the incidence of atrial fibrillation episodes to provide new insights into the long-term benefits of this pacing technique. The study addresses a gap in the literature regarding the long-term results of CSP.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term effectiveness and safety of conduction system pacing for patients with conduction disorders.

How similar studies have gone: While there is limited data on long-term outcomes of conduction system pacing, this study is designed to fill a significant gap in existing research.
