Figure 4. AP prolongation by veratridine in human iPSC-derived cardiomyocytes.

Figure 4.

Current-clamp AP recordings using a pacing protocol with injected current stimuli of 0.5-ms duration and 2 nA amplitude repeated at 3-s intervals. The overlap of traces in control conditions at the start of the experiment, with 1 μM veratridine (onset and full effect), with 5 μM veratridine, and during wash-out, shows partial recovery.
