Decreased Upright Cerebral Blood Flow and Cerebral Autoregulation in Normocapnic 1 Postural Tachycardia Syndrome


22 The postural tachycardia syndrome (POTS), a chronic form of orthostatic intolerance, has 23 signs and symptoms of lightheadedness, loss of vision, headache, fatigue, and neurocognitive 24 deficits consistent with reductions in cerebrovascular perfusion. We hypothesized that young, 25 normocapnic POTS patients exhibit abnormal cerebral autoregulation (CA… (More)
