Orthostatic cerebral hypoperfusion syndrome (OCHOs). The tilt provoked a progressive increase in BP that was seen in both finger (black trace) and arm (green boxes) BP. The finger systolic BP exceeded the upper range of our device, 205 mmHg. The CBFv was progressively declining during the tilt that was consistent with cerebral vasoconstriction. Patient was very dizzy and agitated during the tilt. Data from 66-year-old woman.
