Can ECG algorithms pinpoint dangerous heart rhythms in tetralogy of fallot patients?
NCT ID NCT07607821
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study checks whether three common ECG-based methods can accurately locate where abnormal heart rhythms start in adults who had Tetralogy of Fallot repair. Researchers will pace the heart from known spots during a scheduled procedure and compare the predicted location to the real one. The goal is to see if these methods work in hearts with different structure, helping doctors plan better treatments.
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 study could help doctors trust existing ECG methods for planning arrhythmia treatments in Tetralogy of Fallot patients, or show that new methods are needed.
- What could go wrong
- This is a small, early-stage study with only 30 participants, so results may not apply to all patients. The algorithms may still prove inaccurate in this population.
