Heart rhythm mystery: new study maps hidden triggers of persistent AF
NCT ID NCT04041778
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 17 adults with persistent atrial fibrillation (a long-lasting heart rhythm problem) to find specific areas in the heart that may keep the condition going. Researchers used special mapping to identify stable high-frequency electrical signals. The goal was to better understand what causes persistent AF, so future treatments can be more effective.
