This study looks at the long-term safety and effectiveness of a medical device called the QDOT MICRO™ system used with the VISITAG SURPOINT™ Module to treat a heart condition called paroxysmal atrial fibrillation (PAF). PAF is when the heart beats irregularly and can stop on its own within 7 days. This study is for adults (18+) who have tried medicine that didn't help their PAF. Patients will have check-ups 1 year after treatment, and then 2 more times at 2 and 3 years.
- **Study Length:** Up to 3 years with multiple follow-ups.
- **Participation Requirements:** Prior consent and meeting specific health criteria.
- **Exclusions:** Prior heart ablation and current trial participation.
