Figure 1 Mean regional EF for (a) ischemic (n = 70) and (b) nonischemic (n = 116) LV sectors before, during and after two exercise tests 30 min apart. Closed circles = first exercise test; open circles = second exercise test; error bars = standard error of the mean. *p < 0.05 versus equivalent time point for first test using Wilcoxon signed rank test with Bonferroni correction.
