Noninvasive assessement of maternal hemodynamic function by electrical impedance cardiography (EIC) and correlation with uterine and umbilical vascular resistance in mid-pregnancy.


Maternal systemic hemodynamics can be conveniently acquired by EIC at the same time as routine obstetrical imaging. Our data suggest that maternal cardiovascular adaptation more closely reflects the fetoplacental circulation than the uteroplacental circulation in women at moderate risk of preeclampsia. EIC may be a useful adjunct in assessing risk of fetal compromise.
