Cerebral Blood Flow, Heart Rate, and Blood Pressure Patterns during the Tilt Test in Common Orthostatic Syndromes

Figure 20

The transient drop in BP at the beginning of the tilt (designated by a green box) is artificial. The oscillometric device showed much higher BP (the small filled green box in (b)). Another clue that this is a technical artifact is the fact that there is no corresponding HR reaction and also CBFv is unchanged. The tilt test was normal. Data from 38-year-old woman.
