Screening for Atrial Fibrillation With Electrocardiography US Preventive Services Task Force Recommendation Statement

摘要

IMPORTANCE Atrial fibrillation is the most common type of cardiac arrhythmia (irregular heartbeat), and its prevalence increases with age, affecting about 3% of men and 2% of women aged 65 to 69 years and about 10% of adults 85 years and older. Atrial fibrillation is a major risk factor for ischemic stroke, increasing risk of stroke by as much as 5-fold. Approximately 20% of patients who have a stroke associated with atrial fibrillation are first diagnosed with atrial fibrillation at the time of stroke or shortly thereafter.
