Figure 3. Effect of Vx on Purkinje fiber action potential waveforms.

Figure 3

Superimposed records before (control) and after sequential 20 minute equilibration periods with Vx at the indicated concentrations (0.01, 0.1 and 1 μM). Temperature = 37 ± 1 °C, BCL = 2 s. Vx did not cause significant changes in any of the measured action potential parameters (n=3).
