What this trial studies

This study aims to evaluate the effectiveness of the CardiaCare™ RR2 wearable home-care neuromodulation system in reducing the burden and symptoms of paroxysmal atrial fibrillation (AF). Participants will undergo a 14-day screening with continuous ECG monitoring before being randomized into either an active treatment group or a sham treatment group. Over a 12-week treatment period, patients will conduct self-administered neuromodulation sessions and perform daily ECG recordings. After 10 weeks, participants will wear an ECG patch continuously for an additional 14 days to monitor their condition.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 18-85 with documented paroxysmal atrial fibrillation and a specific AF burden.

Not a fit: Patients with hemodynamic instability, recent myocardial infarction, or certain heart block conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the frequency and severity of AF episodes for patients.

How similar studies have performed: While similar neuromodulation approaches have been explored, this specific application in paroxysmal AF is relatively novel.
