What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study follows 1,200 people in China with atrial fibrillation who are getting a new type of procedure called pulsed field ablation. Researchers want to see if early heart rhythm problems after the procedure can predict if the condition will come back later. Participants will have regular check-ups and heart monitoring for one year to gather this information.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help doctors better predict who will have a return of atrial fibrillation after pulsed field ablation, leading to more personalized follow-up care.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly test a new therapy. Results may not apply to all patients or settings.

Who is studied

Consecutively selected patients with atrial fibrillation who underwent pulsed field ablation (PFA) in the Department of Cardiology at West China Hospital of Sichuan University from June 2025 to June 2026. Patients were screened strictly in accordance with the inclusion and exclusion criteria to enroll eligible participants as study subjects.
