This study is looking at how two different methods of catheter ablation affect the temperature of your esophagus (the tube connecting your throat to your stomach) during a procedure for paroxysmal atrial fibrillation (a type of irregular heartbeat). Researchers will compare the QDOT Micro ablation catheter with the ST SF ablation catheter. The main goal is to see which method causes the smallest change in esophageal temperature during the ablation procedure. You may be able to join if you are 18 years or older and have been diagnosed with paroxysmal atrial fibrillation. The current recruitment status is unclear, and the study plans to enroll 30 participants.

Study design

This is a randomized controlled trial, meaning participants will be randomly assigned to one of two treatment groups. The study plans to enroll 30 participants.

What's involved

Not specified in the trial record.

Compensation

Not stated in the trial record.

Follow-up

The primary endpoint, maximal change in esophageal temperature, is measured during the ablation procedure. Esophageal injury will be assessed by post-procedure capsule endoscopy.
