Symptom severity assessment in patients with atrial fibrillation after catheter ablation using a smartphone application
- Secondary analysis of the ISOLATION study
Authors' conclusion
Smartphone-based symptom severity assessment after AF ablation is feasible and reveals substantial individual variability beyond rhythm status alone.
