Clinical Trial Summary

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.

Secondary	AF burden defined as the total number of symptomatic AF events during screening period compared to end of treatment period		14 weeks
Secondary	Change from baseline compared to end of treatment period in Life quality & symptoms as assessed by AF AFEQT(from 0-poor to 100-great), EHRA Score (from I-no symptoms to IV-disabling symptoms) and SF36 questionnaires (form 0-worst to 100-best)		14 weeks
