The values are means ± SEM. Number of rats per group n = 10. Experimental group abbreviations explained in Fig. 1, significant differences vs. C are marked *, significant differences vs. HFFD are marked ^#, for end of stabilization (STAB): QRS ^#p < 0.05 HFFD vs. HFFD-S, QT ^*p < 0.05 C vs. HFFD-S, QTc ^*p < 0.05 C vs. HFFD-S, HFFD-R, for end of ischemia (ISCH): PQ ^*p < 0.05 C vs. HFFD, ^**p < 0.005 C vs. HFFD-S, HFFD-R, for end of reperfusion (REP): PQ ^*p < 0.05 C vs. HFFD-R, ANOVA, Bonferroni comparison test.
