Detection and analysis of VA in the four groups of rats. a Pseudo-ECG before and during VA initiated by pacing at 100-ms BCL. T-wave alternans (shown with arrows) was found prior to VA initiation. b The panels show eight snapshots of the phase maps, which correspond to the time points indicated in red points of the amplified pseudo-ECG episode. The positions of phase singularities (PSs) are indicated by the white circle. The formation of the rotor, a hallmark of re-entrant VA, was observed in MCT-treated RVs. c Inducibility of VA in each group. VA ventricular arrhythmia, BCL basic cycle length, n = 10 per group. χ2 tests. *p < 0.05, **p < 0.01
