Response of Type I Atrial Fibrillation (AF) to Atrial Pacing in Humans
American Heart Association
Local right atrial capture is often possible by pacing during type I AF and consistently influences the left atrial electrograms recorded in the coronary sinus. These results confirm the presence of excitable tissue in the right and left atria in type I AF.

Local Capture by Atrial Pacing in Spontaneous Chronic Atrial Fibrillation (AF)
American Heart Association
During spontaneous chronic AF in Humans, (1) local capture by atrial pacing is possible up to 15mm from the pacing site, (2) regional entrainment is possible during type 1 and type 2 AF but not type 3 AF, and (3) pacing before capture accelerates AF, probably by transient or local capture. These findings suggest that an excitable gap is present in chronic AF, therefore supporting the hypothesis that leading circle reentry is not the unique electrophysiological mechanism maintaining the arrhythmia.
