[24-hour blood pressure determination in Shy-Drager syndrome. A case report].

The case history is presented of a 57 year-old male patient suffering from the Shy-Drager syndrome. This syndrome was first described by G. M. Shy and G. A. Drager in 1960. The clinical manifestations are extrapyramidal, with Parkinsonian features, combined with severe orthostatic hypotension and failure of the autonomic nervous system. Apart from the standard clinical investigations in this condition, namely the orthostasis test and polygraphic recording of the EEG, ECG, breathing and blood pressure on the tilting table, additional non-invasive long-term determination of the blood pressure was carried out. This method allows simultaneous measurement of blood pressure and heart rate without appreciably interfering with the patient's daily activities.
