The meander of RAs is lowest in PF and reduces with enhanced GJ coupling. Representative tracked paths of the longest duration RA (threshold—>5 rotations) in (A) RTG-treated group and (B) differing fibrosis groups; CF, DiF, and PF (left) and the corresponding centre shift from initiation to termination site over time (right). Data from RTG (n = 10) treated hearts in (A) and sham surgery (n = 5), CF (n = 11), DiF (n = 11), and PF (n = 13) hearts in (B). Statistical analysis with repeated measures ANOVA, post hoc Bonferroni, P-values are in comparison to baseline in (A) and ANOVA, post hoc Bonferroni multiple comparisons test in (B). *P < 0.05 and ***P < 0.001.
