[The orthostatic test with arterial hypertension patients].

The initial level of the systolic and diastolic arterial pressure (AP) effects the character and value of changes of these indices during the orthostatic test. With elevation of the initial AP level both the healthy and patients with arterial hypertension (AH) showed a tendency to a more pronounced reduction of the systolic AP and to a lesser increase of the diastolic AP in the orthostatic position. In-equal initial AP, patients with AH did not reveal any characteristic differences as compared with the healthy in the response of the AP to orthostasis.
