CHADS-65

CHADS-65 is a score that is positive if the person is over 65 years, has diabetes, has high blood pressure, has heart failure, or has had a stroke or TIA.^[1] For those with atrial fibrillation who have one of these criteria anticoagulation is generally recommended.^[1]

In those who have an episode of atrial fibrillation for 12 to 48 hours, if they have either 0 or 1 criteria, they may be cardioverted safely.^[1] Whether or not those with a score of 0 should be anticoagulated for 4 weeks after cardioversion is controversial; though may be carried out on a case by case basis as of 2021.^[1]
