Popis: | Of 20 patients with idiopathic orthostatic hypotension (IOH), four manifested marked spontaneous fluctuations in arterial pressure when in the supine position (supine blood pressure). Blood pressure (intra-arterial recording) varied from 20 to 80 per cent between hemodynamic studies. The only significant difference between the lowest and highest pressure was in total peripheral resistance, which was 32 and 49 U · m 2 respectively (P |
