Ca_i²⁺ alternans parameters for monolayers in which spiral wave reentry did and did not occur. A: average values for PCL_C, PCL_D, and MCL. B: average values for AVW and AVW_D. The four groups were averaged over all temperature conditions, CT, RT, and the subset of RT monolayers after the addition of Pin. Monolayers mapped at PT were not included because no alternans was induced. For each group, the average values are plotted for monolayers in which no reentry (solid bars) or reentry (open bars) occurred. Error bars show SEs. *Statistically significant difference (P < 0.05) of no reentry compared with the corresponding reentry group.
