Figure 4 Scatter plots of the maximum gradient of repolarization (GR_max) in the epicardial (Epi) and endocardial (Endo) surfaces (A) and transmural dispersion of repolarization (DR) (B) in control and the ST-segment elevation (Brugada-ECG) condition with (closed circles) or without (open circles) phase 2 re-entrant (P2R) extrasystoles. Values are mean ± SD. *p < 0.05 versus control condition; ${dagger}$ p < 0.05 versus Brugada-ECG condition without P2R-extrasystole by analysis of variance with Scheffe’s test.
