Read our Atrial Fibrillation research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study compares three different ways to use the QDOT Micro catheter, a specialized tool that treats atrial fibrillation (irregular heartbeat) by creating precise burn lines in the heart. Each approach uses a different power level—standard power, very high power, or a combination of both. The goal is to find which method works best and is safest for patients having their first ablation procedure.
Doctors know that ablation works well for atrial fibrillation, but they don't yet know whether using higher power settings might make the procedure faster, more effective, or safer. This trial will help answer that question so future patients can benefit from the best approach.

You will be randomly assigned to receive ablation using one of the three power settings for the QDOT Micro catheter. During the procedure, doctors will use special stabilization techniques to help position the catheter precisely. The procedure itself works the same way regardless of which power setting you receive—the main difference is how much energy is used to create the burn lines that treat your irregular heartbeat.
