Implantable loop recorders (ILRs) are increasingly being used for long-term cardiac monitoring in different clinical settings. The aim of this study was to investigate the real-world performance ILRs-including time diagnosis- unselected patients with ILR indications. In multicenter, observational study, 871 an indication pre-syncope/syncope (61.9%), unexplained palpitations (10.4%), and atrial fibrillation (AF) detection a history cryptogenic stroke (CS) (27.7%) underwent implantation. median follow-up 28.8 ± 12.9 months. presyncope/syncope group, 167 (31%) received diagnosis established by device. Kaplan-Meier estimates indicated that 16.9% had at 6 months, proportion increased 22.5% 1 year. Of 91 palpitations, 20 (22%) based on 12.2% 13.3% Among 241 CS, 47 (19.5%) were diagnosed AF. diagnostic yield device 10.4% months 12.4% all cases, oral anticoagulation initiated. Overall, altered therapeutic strategy 26.1% 2.2% 3.7% CS group addition initiation. patient population, determines initiates new management nearly one fourth patients. implantation is valuable evaluation presyncope/syncope, palpitations.
