Summary

This study tested whether sending mild electrical pulses just under the skin could help control heart rate in people with atrial fibrillation (AFib). 46 adults with symptomatic paroxysmal AFib who didn't respond to standard drugs were given a device implant. For two weeks, some received active stimulation while others got a sham treatment. Researchers measured changes in AFib burden and heart rate control using mobile heart monitors.
