Figure 1 Changes of MAP during a 60° head-up tilt-table test (HUT) in a patient with Shy-Drager syndrome (Patient 4). Syncope occurred after 10 min during conventional nonpharmacological and pharmacological treatment (lower line), whereas a symptom-free 45 min test was possible with the patient-controlled, ambulatory norepinephrine treatment (upper line). Heart rate remained stationary in both cases. MAP = mean arterial blood pressure.
