Before exercise, only V-POTS subjects had significantly higher standing HR and ΔHR than all other groups. After exercise, O-START and V-START had significantly higher standing HR and ΔHR than control and STOPP groups, while V-POTS was significantly higher than all other groups. Blood pressures did not differ.

P < 0.05 for V-POTS vs. all other groups by one way ANOVA followed by post-hoc Tukey’s HSD.
