Atrial Fibrillation Mapping at Sites of Termination

Characteristic	Entire Cohort	Terminations to Sinus Rhythm (n=32)	Terminations to Atrial Tachycardia (n=23)	P Value
Site of AF termination
Left atrial/right atrial	48/7
Technique 1 (phase); no. of cycles/index map	N=55; 11.1±4.3
No. sources (LA/RA)	(45/6)	(29/3)	(16/3)	0.66
Activation at AF term site
Rotational	48	30	18	0.16
Focal	3	2	1
Disordered (ie, no source)	4	0	4
Technique 2 (activation/phase); no. of cycle/index map	N=55; 12.7±3.7
No. sources (LA, RA)	(48/7)	(29/3)	(19/4)	0.43
Activation at AF term site
Rotational	52	30	22	0.96
Focal	3	2	1
Disordered (ie, no source)	0	0	0

AF indicates atrial fibrillation; LA, left atrium; and RA, right atrium.
