flag Field Medical's new ablation tech isolated pulmonary veins in under 8 minutes with no serious side effects, showing promise for treating atrial fibrillation.

flag Field Medical presented late-breaking data from its first-in-human Field PULSE trial at the 2026 International AF Symposium, showing its high-voltage pulsed field ablation system created lesions in under 200 milliseconds, enabling rapid pulmonary vein isolation in as little as 7.7 minutes. flag The procedure demonstrated strong safety, with no serious adverse events, kidney injury, phrenic nerve damage, or hemolysis, and no silent brain lesions found in MRI scans. flag PVI durability improved over time, supporting the technology’s potential for treating atrial fibrillation and other arrhythmias across heart chambers.
