Exercise showdown: HIIT vs. moderate workouts for AFib patients
NCT ID NCT03397602
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two types of supervised exercise programs—high-intensity interval training (HIIT) and moderate-intensity continuous exercise—against standard care alone in 132 adults with persistent or permanent atrial fibrillation. Participants will exercise twice weekly for 12 weeks. The goal is to see which approach better improves exercise capacity and quality of life.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
exercise training (moderate-intensity continuous or high-intensity interval)
What this could lead to
If it works, this could point toward a simple, drug-free way to improve fitness and daily well-being for people with atrial fibrillation.
What could go wrong
This is a relatively small, early-stage trial (132 participants) comparing two exercise programs. Results may not apply to all AF patients, and exercise benefits can vary widely.
