Résumé
Reduction of atrial fibrillation (AF) burden is the preferred outcome measure over categorical AF rhythm recurrence after AF ablation. In this sub-analysis of the TeleCheck-AF project we tested the feasibility of smartphone app-based approximation of time spent with AF and/or symptoms. Patients scheduled for at least one teleconsultation during the 12-month follow-up after AF ablation were instructed to use a smartphone photoplethysmography (PPG)-based application for simultaneous symptom and rhythm monitoring 3-times daily for 1 week. Proxies of time spent with AF and/or symptoms (%-recordings, load, %-days), temporal aggregation of AF and/or symptoms (density), and symptom-rhythm correlation (SRC) were assessed. In total 484 patients (60% male, 62±9.9 years) were included. Adherence, motivation and patient satisfaction were high. %AF-recordings, AF load and %AF-days (rs= 0.88-0.95) and %symptom-recordings, symptom load, %symptom-days (rs= 0.95-0.98) showed positive correlations. The SRC correlated negatively with time spent with symptoms (rs=-0.65--0.90) and with time spent with AF (rs=-0.31--0.34). In patients with paroxysmal AF before ablation and AF during the monitoring period, 87% (n=39/44) had a low-density score <50% ("paroxysmal AF pattern") while 5% (n=2/44) had a high-density score >90% ("persistent AF pattern"). Corresponding numbers for patients with persistent AF before ablation were 48% (n=11/23) and 43% (n=10/23), respectively. On-demand, app-based simultaneous rhythm and symptom assessment provides objective proxies of time spent with AF and/or symptoms and symptom-rhythm correlation, which may assist in assessing AF and symptom outcomes after AF ablation.

BACKGROUND AND AIMS
OBJECTIVE
Reduction of atrial fibrillation (AF) burden is the preferred outcome measure over categorical AF rhythm recurrence after AF ablation. In this sub-analysis of the TeleCheck-AF project we tested the feasibility of smartphone app-based approximation of time spent with AF and/or symptoms.
METHODS
METHODS
Patients scheduled for at least one teleconsultation during the 12-month follow-up after AF ablation were instructed to use a smartphone photoplethysmography (PPG)-based application for simultaneous symptom and rhythm monitoring 3-times daily for 1 week. Proxies of time spent with AF and/or symptoms (%-recordings, load, %-days), temporal aggregation of AF and/or symptoms (density), and symptom-rhythm correlation (SRC) were assessed.
RESULTS
RESULTS
In total 484 patients (60% male, 62±9.9 years) were included. Adherence, motivation and patient satisfaction were high. %AF-recordings, AF load and %AF-days (rs= 0.88-0.95) and %symptom-recordings, symptom load, %symptom-days (rs= 0.95-0.98) showed positive correlations. The SRC correlated negatively with time spent with symptoms (rs=-0.65--0.90) and with time spent with AF (rs=-0.31--0.34). In patients with paroxysmal AF before ablation and AF during the monitoring period, 87% (n=39/44) had a low-density score <50% ("paroxysmal AF pattern") while 5% (n=2/44) had a high-density score >90% ("persistent AF pattern"). Corresponding numbers for patients with persistent AF before ablation were 48% (n=11/23) and 43% (n=10/23), respectively.
CONCLUSIONS
CONCLUSIONS
On-demand, app-based simultaneous rhythm and symptom assessment provides objective proxies of time spent with AF and/or symptoms and symptom-rhythm correlation, which may assist in assessing AF and symptom outcomes after AF ablation.
