Basis for the Induction of Tissue-Level Phase-2 Reentry as a Repolarization Disorder in the Brugada Syndrome

Figure 2

Space-time plots and wave profiles for three cases of phase-2 reentry (P2R) in one-dimensional epicardial cables. (a) Antidromic (retrograde) P2R generated by a propagating wave initiated from the lost-dome region (red) using Model 1. (b) Orthodromic (forward) P2R generated by a propagating wave initiated from the delayed-dome region (blue) using Model 1. (c) Antidromic P2R generated by a propagating wave initiated from the lost-dome region (red) using Model 2. In all cases, P2R originates slightly away from the interface between the lost-dome and delayed-dome regions (horizontal scale bar, 1 cm).
