Quantification analysis of CFAE sites during AF, SR and CS-pacing.

	PAROXYSMAL AF	PERSISTENT AF	p-Value
CFAE as percentage of total LA surface area
AF	19±9%	27±4%^*	0.01
SR	19±6%	21±7%^*	0.55
CSp	14±5%	21±12%	0.16

Overlap between CFAE in different rhythms as percentage of total LA surface
AF and SR	3+/−1%	4+/−2%	0.09
AF and CSp	1+/−1%	5+/−2%	<0.001
SR and CSp	4+/−2%	6+/−2%	0.16

CFAE regions in AF also fractionated in SR and CSp
SR	16+/−4%	15+/−5%%	0.93
CSp	6+/−3%	18/−7%	<0.001

In patients with PsAF, there is a significantly higher extent of continuous CFAE sites in AF versus the extent of fractionated LA surface in sinus rhythm (CFAE at 27+/−4% of the total LA surface vs. fractionation at 21+/−7% during sinus rhythm, p=0.048).
