Figure 3. The effects of treatment on the volume–pressure capacitance relationship in neuropathic POTS (A) and hyperadrenergic POTS (B).

Figure 3

As shown in (A), midodrine blunted the capacitance curve in neuropathic POTS. Shown in (B), placebo increased capacitance in hyperadrenergic POTS. *P < 0.05 and †P < 0.01 compared with pre-treatment and cross-over treatment.
