First seen Nov 01, 2025 · Last updated May 15, 2026 · Updated 26 times

Summary

This study tested a special catheter device to treat people with a type of irregular heartbeat called paroxysmal atrial fibrillation that didn't get better with medication. The device uses energy to isolate the veins that trigger the abnormal rhythm. Researchers measured safety by tracking side effects within a week and effectiveness by checking if the irregular heartbeat returned. The study involved 237 participants and aimed to improve quality of life.
