Digital Health and Remote Monitoring in Atrial Fibrillation Management: A Systematic Review

Abstract 2294802, presented at Western Atrial Fibrillation Symposium 2026

Telehealth and remote monitoring technologies may improve early detection of arrhythmia recurrence, medication adherence and patient engagement in AF management. Evidence on their efficacy and safety is variable.Randomized and cohort studies (January 2010–August 2025) assessing digital tools such as smartphone applications, telemonitoring platforms and implantable loop recorders in AF management were identified through PubMed and Embase. Primary outcomes included time to detection of recurrence, adherence to anticoagulation, AF‑related hospitalizations and patient satisfaction.Nineteen studies with 3,500 participants were included. Remote monitoring reduced median time to detection of recurrent AF by 45–60 days and improved anticoagulation adherence by 12%. Three of six trials reported a reduction in AF‑related hospitalizations (relative reductions of 18–30%); no study reported increased adverse events. Patient satisfaction was generally high, but digital literacy influenced uptake and adherence.Digital health interventions facilitate earlier detection of recurrence and modestly improve medication adherence in AF management. Heterogeneity in technology and study design limits definitive conclusions; future research should evaluate cost‑effectiveness and integration into routine care.
