Is waiting safe for AFib? new study tests delayed treatment
NCT ID NCT04267159
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether it's safe to wait 5-9 days before treating a sudden episode of atrial fibrillation or flutter, instead of treating it right away in the emergency room. About 500 patients who are stable enough to go home will be randomly assigned to either immediate treatment or delayed treatment at a clinic visit. The goal is to see if both approaches are equally safe and effective at restoring normal heart rhythm.
