I_HERG waveforms and I–V relationships measured by AP-clamp.

<p>Left panels: Typical examples of current waveforms recorded by AP-clamp; Right panels: I–V relationships averaged from at least 15 cells. Dash lines indicate the voltages at which I_HERG peaks (V_Peak). The mean V_Peak was averaged from 15 cells for each group. *<i>p</i><0.05 <i>vs.</i> Endo.
