Cycle length mapping for long-term atrial fibrillation
Part of Heart & circulation clinical trials.
This study tests a new mapping technique to find chaotic electrical signals in the heart during persistent atrial fibrillation. It may help doctors better target treatment for people whose atrial fibrillation does not stop with medication.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have atrial fibrillation that lasts more than 7 days or needed a procedure to stop it.
- You have tried at least one heart rhythm medication (like flecainide or amiodarone) but it didn't work or caused side effects.
- You are 20 to 90 years old.
- You do not have a blood clot in your heart or an allergy to contrast dye used in imaging.
- You are not pregnant, on dialysis, or unable to receive X-rays.

This study tests a new approach for people with atrial fibrillation (a type of irregular heartbeat) who are also at high risk for stroke. It combines a procedure to fix the heart's electrical signals with closing off a small pouch in the heart to reduce stroke risk, potentially avoiding long-term blood thinners.
This trial tests a new way to map the heart's electrical signals to help doctors better target and treat atrial fibrillation (an irregular heartbeat). If you're having a procedure to treat AF, this study may help improve the success of your treatment.
This trial tests a new system that maps and treats atrial fibrillation using special energy (pulsed field ablation) during a repeat ablation procedure. It also uses a small implanted monitor to track your heart rhythm before and after the procedure, which may help improve outcomes.
This trial tests whether using a special heart-mapping device during ablation (a procedure to fix irregular heartbeats) can improve outcomes for people with persistent atrial fibrillation and an enlarged left heart chamber.
This study compares two techniques for treating persistent atrial fibrillation: one uses standard anatomy-based ablation, and the other uses a special mapping system to guide the procedure. It aims to find which method works better for people who have not had prior ablation.
This trial tests a new balloon catheter that uses pulsed electric fields to treat persistent atrial fibrillation, a type of irregular heartbeat that lasts more than 7 days. The treatment aims to restore normal heart rhythm and may be an option for people who have not had prior heart procedures.
