Electrophysiological and Electroanatomical Mapping of the Right Atrium in Persistent Atrial Fibrillation: Relation to Collagen Turnover

摘要

BackgroundAtrial fibrillation (AF) is associated with abnormal atrial substrate. We investigated whether patients with persistent lone AF and patients with persistent AF and nonischemic dilated cardiomyopathy (NIDCM) exhibit any differences in electrophysiological and electroanatomical properties of right atrium (RA) and collagen turnover. We also investigated the relationship between mean RA bipolar voltage and collagen turnover.
