Detecting Orthostatic Intolerance in Long COVID in a Clinic Setting Isaac, Robert Oliver; Corrado, Joanna; Sivan, Manoj Introduction: A likely mechanism of Long COVID (LC) is dysautonomia, manifesting as orthostatic intolerance (OI). In our LC service, all patients underwent a National...

Abstract 50% of POTS patients are hypocapnic during orthostasis related to initial orthostatic hypotension (iOH). We determined whether iOH drives hypocapnia in POTS by low BP or decreased cerebral blood flow velocity (CBFv). We studied 3 groups; healthy volunteers (N=32, 18±3y) were compared...
