Representative bipolar electrogram (BEG) recordings during programmed electrical stimulation (PES) before (A) and 120 s after (B) introduction of 2 mM heptanol. Activation latencies from BEG recordings obtained before (clear bar; n = 5) and 120 s after (black bar; n = 5) introduction of 2 mM heptanol (C). The asterisk indicates these were significantly increased by 2 mM heptanol (ANOVA, P < 0.05)
