Definition of the ‘patchy’ LGE site
The LGE site was classified into the dens or patchy LGE site. An animal
study reported that the maximum gap length with conduction block was 4
mm.10 According to the
result, the patchy LGE site was
defined as the site where the at least two small LGE could distributed
within 5mm diameter (Figure 2). Based on this definition, the patchy LGE
site appeared inhomogeneous infiltration of atrial tissue by LGE, while
the dense LGE site appeared homogenous and strong infiltration of atrial
tissue by LGE.
