About
Determine the role of vagal/median nerve stimulation using the CardiaCare RR2 home care wearable neuromodulation system on suppressing atrial arrhythmias and related symptoms in patients who have undergone AF ablation. The study population will be comprised of adults (age ≥18 yrs.) who have undergone AF ablation for paroxysmal or persistent AF.
The study will assess the ability of neuromodulation, using the CardiaCare RR2 home care wearable, to suppress the following:
- early (0-2 months) post-ablation arrhythmias that occur in the immediate post-ablation time period
- AF/AT/AFL recurrences between months 2-6 post-ablation.This is a prospective, controlled, double-blind, randomized trial. The first 15 patients will not be randomized and will receive the active median/vagal stimulation only (open label).
The Study will be conducted in up to 1 clinical site in the United States. This study will have 1:1 randomization (active median/vagal stimulation vs sham). The study has been given NSR designation from FDA--NO IDE.
Full description
Study will include continuous ECG assessment at 2 (0 for the first 15 patients, open label), 6 and 22 weeks from enrollment for 2 weeks (for 4 weeks at the first measurement for the first 15 patients, open label) and at least daily single lead ECG assessments throughout the follow up period. The ECG's generated can be viewed by physicians only to assess the frequency of RR2 treatments and will not be used to alter any other aspects of standard of care, including medical management, which will continue according to standard of care throughout the study. Patients and investigators will be blinded during the trial. Patients with paroxysmal or persistent AF undergoing AF ablation will be recruited post ablation procedure during hospitalization. During screening/baseline visit, eligible patients will be randomized to either an active treatment or a sham group (1:1 accordingly). The first 15 eligible patients will not be randomized and will receive the active median/vagal stimulation only (open label).
Patients will receive training on the RR2 for home-care use, by study personnel either in person or via a video conference meeting. An instructional video will also be available for users. Patients will be ordered to measure at home, 2 min ECG measurements with the RR2 system, two times a day throughout the study and when feeling symptoms suspected related to AF (AF/AT/PAC).
In addition, Patients will be instructed to perform Neuromodulation sessions with the RR2 home care device. Once a day for the first 2 weeks followed by three times per week for the remaining duration of the study. Additional treatments, up to once daily, will be added during this period in case the patient feels symptom, verified on single lead ECG and site staff.
Treatments will be conducted for a period of 6 months. During the study, the patients will continue to take Standard of care medication. Medications will be recorded throughout the study.
Patient Diary will be dispensed and or APP diary questioners will be used by the subject in order to document symptoms suspected as related to arrhythmia events.
