Cerebral Blood Flow, Heart Rate, and Blood Pressure Patterns during the Tilt Test in Common Orthostatic Syndromes
Figure 13
Orthostatic hypertension syndrome. BP was elevated during the tilt while CBFv was stable. HR responses were normal during the tilt. Note increased cerebral vascular resistance (CRV) that is consistent with cerebral vasoconstriction. Data from 39-year-old man.
