Commentary on Twitter

Great new research from Vanderbilt documenting that a high salt diet reduces standing tachycardia and norepinephrine levels in POTS, but that even with a high salt diet, POTS patients have lower blood volume than healthy individuals. https://t.co/Fy4UcPmOyB pic.twitter.com/2ozUxzK8f6
