Changes were recorded in central and periphery haemodynamic indices during the uncomplicated pregnancy, at the onset of preeclampsia, and postpartum, in the relevant studies made. The following three cardiodynamic phase syndromes were found to be developing through stages during physiological pregnancy against the background of hypervolemia: volume loading under 22 to 24 weeks, hyperdynamic state at 28 to 32 weeks, and hypodynamic one antepartum. Preeclampsia is associated with changeable haemodynamic indices, which fact is chiefly hypervolemia-related. The pump function of the heart becomes inadequate and the cardiodynamic phase syndrome of high diastolic pressure in noted to be developing. Early significant indices for preeclampsia have been determined characterizing the latent blood circulation deficiency in the preclinical stage. This warrants the use of a non-invasive method, such as, for instance, tetrapolar bioimpedance integral rheography for a complex programme of prophylaxis and treatment of preeclampsia to be instituted.
