Increased Dispersion of Refractoriness in Patients with Atrial Fibrillation in the Early Postoperative Period after Coronary Artery Bypass Grafting

Abstract

AERP dispersion is a suitable electrophysiologic indicator for atrial vulnerability. The presence of increased preoperative AERP dispersion and PA interval may indicate patients at high risk for development of AF in the early postoperative period after coronary artery bypass grafting.
