Trends in the use of implantable loop recordertrends and diagnostic rate of the implantable loop recorder in nationwide database

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main source(s): Korea University Introduction Implantable loop recorder (ILR) is useful to reveal hidden arrhythmia. The real-world using trend ILR implantation and indication were studied nationwide database. Purpose To assess the diagnostic rate meaningful arrhythmia Method We analyzed 1,460 patients who underwent (male 62%, mean age 62±16) from 2008 2019 Health Insurance review assessment service Result embolic stroke undetermined source (ESUS) group, syncope group palpitation 619 (42.3%), 765 (52.3%), 76 (5.2%) as indication, respectively. From 2016 2019, ESUS increased by 14 times 4 times. Among with ESUS, 191 (31%) diagnosed atrial fibrillation within 1 year. Bradycardia needed pacing therapy was revealed in 28%, tachycardia 6% 24% group. predictors (OR: 1.024 per year, CI: 1.006-1.042, p=0.0072) heart failure 2.215, CI:1.357-3.615, p=0.0015). time 3±2 months that anticoagulation 6±3 months. Discussion use for evaluation increasing, 30%. treatment differed
