Summary

This study tests a new device system (TactiFlex SE catheter and Volt generator) that uses pulsed field ablation to treat paroxysmal atrial fibrillation, a type of irregular heartbeat. The goal is to see if the procedure is safe and effective for people whose symptoms haven't improved with medication. 188 participants are enrolled, and the study tracks serious side effects within 7 days and freedom from irregular heart episodes after the procedure.
