Figure 7. Classical orthostatic hypotension. Head-up tilt test performed on 82-year-old-man. Please, note a steep decrease in blood pressure after tilt-up ( -70 mmHg) associated with subjective symptoms of orthostatic intolerance, dizziness and fatigue. Cerebral oximetry (normal values: 60-80%) measured through near-infrared spectroscopy demonstrates progressive fall. Test is terminated after 15 min due to pronounced intolerance symptoms and presyncope.
