Arcinas LA, et al. - In this retrospective observational study involving 222 patients, researchers described the incidence of atrial fibrillation (AF) in older adults with implantable loop recorders (ILRs) for unexplained syncope and identified clinical features correlated with AF in this population. Participants in the study were ≥65 years old, without a history of AF, and received an ILR for unexplained syncope. To compare participants with and without AF, Fisher’s exact test and the Student’s t test were used. Between patients with AF and without AF, age, baseline EKG, and prevalence of hypertension, diabetes, stroke, or ischemic heart disease were not statistically different. According to findings, AF was a common diagnostic rhythm with ILRs for unexplained syncope in this cohort of adults, aged 65 and older. It was more frequently noted in women.
