Hemodynamic and symptomatic effects of acute interventions on tilt in patients with postural tachycardia syndrome.
Gordon VM, Opfer-Gehrking TL, Novak V, Low PA; New Collective Author. Gordon VM, et al. Clin Auton Res. 2000 Feb;10(1):29-33. doi: 10.1007/BF02291387. Clin Auton Res. 2000. PMID: 10750641
Other measures used include volume expansion and physical countermaneuvers. These treatments may influence pathophysiologic mechanisms of POTS such as alpha-receptor dysfunction, beta-receptor supersensitivity, venous pooling, and brainstem center dysfunction. The a …

Salt supplementation in the management of orthostatic intolerance: Vasovagal syncope and postural orthostatic tachycardia syndrome.
Williams EL, Raj SR, Schondorf R, Shen WK, Wieling W, Claydon VE. Williams EL, et al. Auton Neurosci. 2022 Jan;237:102906. doi: 10.1016/j.autneu.2021.102906. Epub 2021 Nov 11. Auton Neurosci. 2022. PMID: 34823150 Free article. Review.
In patients with VVS, salt supplementation is associated with increases in plasma volume, and an increase in the time taken to provoke a syncopal event during orthostatic tolerance testing, with smaller orthostatic heart rate increases, enhanced peripheral va …
