2.7 Relationship between the fibrotic tissue properties and AF rotors
To clarify the relationship between the fibrotic tissue properties and AF rotors, the following were assessed: 1) the distribution of the NPAs, 2) optimal fibrotic heterogeneity and density associated with the NPAs, 3) fibrotic tissue classification according to the fibrotic heterogeneity and density, 4) the incidence of NPAs grouped by the fibrotic tissue properties, and 5) the relationship between the CFAEs and AF rotors.
