Objective: To describe hemodynamic changes in normal pregnancy and postpartum by means of thoracic electrical bioimpedance (TEB).

Methods: Eighteen healthy pregnant women were included in the study. Eight different hemodynamic variables were measured by thoracic electrical bioimpedance, from 12th week of gestation until 6th month of postpartum period.
