The pattern of arterial blood pressure and heart rate were investigated in a patient with progressive autonomic dysfunction and nineteen healthy age-matched controls. A marked postprandial reduction of blood pressure was observed in the patient; this phenomenon was not noted in the control group; besides, the rhythmicity of blood pressure and heart rate were altered with peak values shifted approximately eight hours later with respect to the controls.
