Figure 1 Time course of the percent changes in the atrial effective refractory period (AERP) of the right atrial appendage and intra-atrial conduction time (CT) from the right atrial appendage to the lower right atrial wall at a basic cycle length of 300 ms, and the mean duration of induced atrial fibrillation (AF) in the control (white circles, white bars) and candesartan (black circles, black bars) groups. The degree of AERP shortening was similar between the two groups, the intra-atrial CT in the candesartan group was significantly shorter than that in the control group, and the mean AF duration in the candesartan group was significantly shorter than that in the control group. p < 0.01, *p < 0.05 compared with the control group.
