New algorithm could sharpen view of chaotic heart rhythms during ablation
NCT ID NCT05477602
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study tested a new algorithm that automatically measures the cycle length and complexity of atrial fibrillation (AF) signals during a heart ablation procedure. Researchers collected data from 21 people with persistent AF undergoing ablation. The goal was to see if the algorithm, built into a recording system, could provide useful information to guide treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this algorithm could help doctors better understand and treat persistent atrial fibrillation during ablation procedures.
- What could go wrong
- This was a small, completed study focused on data collection, not treatment. The algorithm may not improve patient outcomes or be adopted widely.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Subjects undergoing RF ablation indicated by the investigator for the treatment of persistent atrial fibrillation. * Male or non-pregnant female aged ≥ 21 years. * Able and willing to provide written informed consent prior to any clinical investigation related procedure. Exclusion Criteria: * Current participation in another investigational drug or device study that interferes with this study. * Presence of other anatomic or comorbid conditions, or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow-up requirements, or impact the scientific soundness of the clinical investigation results. * Life expectancy less than 12 month, in the opinion of the Investigator. * Subjects who, in the opinion of the investigator, are not candidates for this study. * Subjects who, in the opinion of the investigator, are considered part of any vulnerable population.
