Figure 6.

EGM analysis for a PxAF tissue with 20% non-uniform diffuse type 1 fibrosis in (A,B) and a PsAF tissue with 40% type 1 Fnu in (C,D) (type 1 Fnu is represented in Figure 1E) cases. Top row: EGMs aligned with respect to the time correspondent to the maximum slope of the depolarization wave (marked as t = 0 in the x-axis). The vertical dashed lines delimit the time window TW for the R_i,j(t) repolarization signals. Bottom rows: atrial repolarization waves, R_i,j(t), with dots indicating the maximum absolute value $R_{i,j}^A$ of the waves within TW. The horizontal dotted lines represent the optimal threshold R^th found by Se/Sp analysis.
