Caffeine before ablation to study atrial rhythm changes
Part of Heart & circulation clinical trials.
This study gives an IV dose of caffeine around the time of atrial fibrillation (AF) ablation to see how it affects heart “electrical signals” and whether it can trigger AF. It may help doctors understand what could worsen or reveal AF during treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’re an adult age 21 to 90
- You have new or recently started paroxysmal atrial fibrillation and you’re scheduled for AF ablation
- Your heart rhythm is either in normal rhythm or AF that started very recently (within about 1 week, confirmed by documentation)
- You can understand the study and sign informed consent
- You do not have severe caffeine intolerance

Other trials that look related to this one.
This trial looks at whether a special heart rhythm treatment called “ablation” works well when done during certain heart operations. It may help reduce atrial fibrillation (AF) symptoms or future abnormal rhythm episodes for people who are already having surgery.
This study tests advanced technology to improve how atrial fibrillation (AFib) is treated with a heart ablation procedure. It may help patients who are already advised to have AFib ablation by seeing how well the approach works in real clinical practice.
This study tracks results after a heart ablation procedure used to treat atrial fibrillation (an irregular heart rhythm). You may be asked to help by consenting and following the study plan so the researchers can better understand what happens after ablations.
This trial tests whether ondansetron can help people with atrial fibrillation (an abnormal heart rhythm) around the time of elective catheter ablation. It may improve the safety or effectiveness of the procedure by targeting a pathway involved in heart rhythm events.
This trial tests whether an early procedure (catheter ablation) for atrial fibrillation (AF) can prevent strokes in people with a high risk of stroke. The goal is to see if this treatment is safer and more effective than standard care for patients with other health conditions.
This trial tests a new catheter system to treat atrial fibrillation (AF) by creating small scars in the heart to block faulty signals. It may help people with symptoms that continue despite medication and who are scheduled for a standard ablation procedure.
