In a patient with atrial high-rate episodes (AHREs) detected by a device, I would generally only recommend treatment with anticoagulation if the episodes are confirmed as atrial fibrillation or atrial flutter based on an ECG/rhythm strip. Detecting AHREs is important to alert treating clinicians of possible afib and high risk of afib status and warrants further monitoring. There is some evidence that patients with AHREs lasting >24 hours are at high risk of stroke, varying based on CHA2DS2-VASc score, and guidelines suggest that anticoagulation is reasonable in patients with a CHA2DS2-VASc score of 2 or above with AHREs lasting >24 hours, though since the guidelines were published, there have been mixed results in the ARTESIA and NOAH-AFNET...
