FUNCTIONAL SYSTEM “MOTHER-PLACENTA-FETUS“ – MONTHLY BIORHYTHMS IN NORMAL PREGNANCY WITH DIFFERENT PLACENTAL LOCATION

Purpose: The aim of our investigation was to study monthly biorhythms of maternal and fetal blood flow at physiological pregnancy with different placental localization. Methods and Materials: 640 women with physiological pregnancy (221- with right side, 200- with left side, 219– with bilateral placental location) were examined in II and III trimesters. We studied such parameters of blood flow as: S/D ratio, PI, IR in right and left maternal uterine arteries, umbilical artery and assessed frequency-peak parameters of biorhythms: mesor, amplitude, period, acrophase. Results: The greatest amplitude of biorhythms of…
