Atrial Fibrillation Saturday, January 26th, 2013

CIRCULATIONAHA: January 23, 2013

Background—Atrial fibrillation (AF) is a frequent source of cardiac emboli in patients with ischemic stroke. AF may be asymptomatic and therefore undiagnosed. Screening for silent AF seems suitable in risk populations, little is however known on the yield and cost-effectiveness of such screening.

Methods and Results—All inhabitants in the municipality of Halmstad, Sweden age 75-76 were invited to a stepwise screening program for AF. As a first step, participants recorded a 12-lead ECG and reported their relevant medical history. Those with sinus rhythm on 12-lead ECG, no history of AF and at least two risk factors according to CHADS2 were invited to a 2 week recording period using a hand-held ECG asked to record 20 or 30 seconds twice daily and if palpitations occurred.  Read More
