Background: Patient-activated event recorders (ER) can facilitate diagnosis in unclear palpitations, however impact of ER screening on further treatment in (n = 27, 38.0%), behavioral intervention (n = 19, 26.8%), electrophysiology-study/catheter ablation (n = 4, 5.6%), cardioversion (n = 2, 2.8%), implantable cardioverter-defibrillator--implantation (n = 1, 1.4%), and left atrial appendage occluder (n = 1, 1.4%). Conclusions:The investigated cross-sector telemetric network is a feasible approach to detect arrhythmia in patients with palpitations and may have high impact on further treatment, notably in those at risk for stroke due to AF.
