- W42686492 abstract "Background: Previous studies have shown the mechanisms responsible for the initiation and the maintenance of atrial fibrillation (AF) in a variety of animal and human models. However, little is known regarding the termination mechanisms of human AF. This study is aimed to assess the termination mechanisms of AF by evaluating the relationship between AF termination and the left atrial anatomical structures. Methods: We studied 106 patients (86 men, mean age; 61±12 years) with paroxysmal AF (n=80) and persistent AF (n=26). They underwent mapping of the left atrium (LA) and the pulmonary vein (PV) using non-contact mapping system (NCMS). Activation sequences on isopotential color maps at the time of the spontaneous termination of AF were analyzed. Results: We recorded 19 AF terminations in 17 patients. Six terminations were abandoned from the analysis because of the existence of the QRS complex. In 10 (77%) of the residual 13 terminations, the significant prolongation of AF cycle length by 42±29 ms measured ..." @default.
