Figure 5 Electroanatomic voltage mapping according to right atrial regions demonstrating a significant reduction in regional atrial voltage at six of six sites in group A compared with group C and four of six sites in group B vs. C. Triangles = group A; circles = group B; diamonds = group C. *p < 0.05 for group A vs. C; #p < 0.01; for group A vs. C; p < 0.05 for group B vs. C; p < 0.01 for group B vs. C.
