While device-detected AF has been established as a risk factor for stroke, questions remain regarding the appropriate AF episode duration threshold for commencement of anticoagulation. A sub-analysis of the ASSERT study demonstrated a significantly increased risk of stroke or systemic embolism in patients with a device-detected AF episode of at least 24 h, with shorter episodes (6 min–24 h) not correlating with an increase in risk [Al-Gibbawi et al. assessed stroke/transient ischemic stroke (TIA) incidence in a high-risk unanticoagulated CIED patient population with an average CHA
