Arterial and venous constriction in response to 10 Hz stimulation at 20 V, 1 ms and 150 V, 10 μs pulses. a Both stimuli constrict arteries to similar extent, but arteries dilate faster after low-voltage stimulation (*p < 0.01, F(3,34) = 23.24; one-way ANOVA with Tukey-Kramer multi-comparison test). b Veins constrict similarly to arteries at high voltage, but significantly less at low-voltage stimulation (p < 0.01, F(3,34) = 27.31; one-way ANOVA with Tukey-Kramer multi-comparison test on the average vessel diameter during stimulation); N = 7 for 20 V and N = 12 for 150 V stimuli
