Coronary artery occlusion induced temporal changes of the estimated repolarization alternans (ST-segment and T-wave) indices (n = 29 records; N = 17 animals): (A) alternans noise (µnoise), (B) alternans voltage, and (C) Kscore. Time zero indicates the balloon inflation moment. Each bar graph represents 10, 25, 50, 75 and 90 percentiles of the corresponding alternans index values beat-by-beat estimated for all animals for 1 minute time span. Asterisk indicates statistically significant increase after occlusion, compared to before occlusion (p < 0.0001 for the alternans noise, p < 0.0001 for the alternans voltage and p < 0.05 for the Kscore).
