Van de 8.575 metingen bleek 11% actief fibrilleren, waarbij bijna de helft van deze episoden asymptomatisch was. De symptoomernering lag hoger tijdens fibrilleren, bij vrouwen en bij hogere hartfrequenties. Deze digitale methode biedt cardiologen een preciezere kijk op de klachtenlast naast de ritmestatus alleen, wat de opvolging na ablatie kan verrijken.","abstract_original":"AIMS: Symptom severity in atrial fibrillation (AF) influences healthcare use, but conventional assessments lack temporal precision. We evaluated the feasibility of smartphone-based symptom severity assessment after AF catheter ablation and explored predictors and variability of symptom severity. METHODS AND RESULTS: In this analysis of the ISOLATION study, 140 patients used a photoplethysmography-supported smartphone application to record heart rhythm, symptoms, and symptom severity three times daily and when symptomatic for 7 days at 3, 6, and 12 months after ablation. Symptom severity was classified using the modified European Heart Rhythm Association scale. A total of 8575 recordings were analysed, of which 11% showed AF. Median adherence was 67%. Symptom severity was higher during AF, in women, and with higher heart rate. Nearly half of AF recordings were asymptomatic. CONCLUSION: Smartphone-based symptom severity assessment after AF ablation is feasible and reveals substantial individual variability beyond rhythm status alone."}
