Figure 2
Different antidromic P2R modalities corresponding to different values of \(d_w^0\). For each situation, a propagating lost dome impulse in the BrS region (blue) depolarizes the healthy tissue (red). P2R is observed when the electrotonic currents from the healthy region to the BrS region cause a new excitation. (a) \(d_w^0 = 0.43\); P2R generates a delayed dome AP close to the healthy tissue, whereas farther from the healthy tissue a lost dome AP is followed by a new delayed dome AP. (b) \(d_w^0 = 0.4\); P2R generates a delayed dome AP close to the healthy tissue, whereas farther from the healthy tissue the AP dome is lost. (c) \(d_w^0=0.3\); P2R generates a new lost dome AP.
