Figure 8

Effects of GS‐6615 (3 μM) and flecainide (2 μM) in the presence of 4 (panel A), 6 (panel B), and 8 mM (panel C) [K+]O on the duration of the QRS interval at a pacing rate of 60, 180 and 210 bpm. Data (means ± SEM; n=6) are presented as the difference (Δ) in the duration (ms) of QRS intervals in the absence and presence of drugs. *P < 0.05, significantly different from baseline at the same pacing rate; ≠ P < 0.05, significantly different from effects of GS‐6615; repeated measures one‐way ANOVA, with Student–Newman–Keul's test.
