The aim of the present study was to investigate evolution of autonomic function during normal pregnancy without history of hypertension. 23 women of mean age 27,4±4,4 yrs on 12-14 weeks of gestation were examined. Spontaneous baroreflex function (BRS) was analyzed by Finometer device with beat-to-beat blood pressure registration. All measurements were performed at supine rest and 5 minute passive tilt (70). Baroreflex was calculated by sequence technique. 12 women were studies second time on 26-30 week of pregnancy. A normal or increases values of spontaneous baroreflex were observed in early pregnancy with e significant reduction of baroreflex sensitivity during tilt. In late pregnancy restoration of the orthostatic tolerance was accompanied by decrease of BRS.
