Heart reflex test may forecast AFib ablation success

This study looked at 116 people with paroxysmal atrial fibrillation (AFib) who were scheduled for a heart ablation procedure. Researchers measured baroreflex sensitivity—a non-invasive test of the autonomic nervous system—before the procedure. They wanted to see if this measurement could predict whether AFib would come back within a year. The goal is to better understand why AFib returns and to help select patients who are most likely to benefit from ablation.
