Overview
Paroxysmal AF subjects with a documented ECG event of AF will be recruited to the study To assess the efficacy of CardiaCare™ RR2 wearable home-care neuromodulation system in reducing AF burden and symptoms in Paroxysmal AF patients
Description
After screening for 14 days with a continuous ECG monitoring device, eligible patients will be randomized to either active treatment or a sham treatment groups. For a treatment period of 12 weeks, patients will be prompted to self-conduct neuromodulation sessions based on: a. predetermined treatment regimen plus b. a detection algorithm. In addition, participants will measure at home, daily 2 min ECG's with the RR2 system two times a day and when feeling symptoms suspected as AF/AT/SVT or PAC's.
After 10 weeks of treatment patients will be requested to wear an ECG patch continuously for an additional period of 14 days.
Overall patients will participate in the study for 14 weeks.
