Figure 3. Effect of various fatty acids on the voltage dependence of activation in adult rat ventricular myocytes.

Sodium currents were evoked by voltage steps to various potentials from a holding potential of −140 mV to various voltages between −90 mV and +30 mV as depicted in Fig. 2A. The peak current amplitude was plotted against the pulse potential. Points represent typical control data (^) or in the presence of 25 μM fatty acid or benzyl alcohol (•) as indicated.
