The changes occurring in hemodynamics due to the effect of alpha-adreno-blocking agent pyrroxan and beta-blocking agent obzidan were studied in 20 patients with neurocirculatory dystonia and in 20 patients with stage IIB hypertensive disease. Forty healthy persons formed the control group. The results of the investigation allow for the assumption that a pharmacological test with a record of the transthoracic rheogram and the derivatives of the central pulse tracings help in the proper choice of the drug and its dosage with the state of hemodynamics and the inotropic myocardial reaction taken into account.
