  1. Parameters of maternal cardiovascular function as measured by impedance cardiography (ICG) in uncomplicated pregnancy (UP), gestational hypertension (GH), late- and early-onset preeclampsia (LPE and EPE, respectively). SBP = systolic blood pressure, DBP = diastolic blood pressure, MAP = mean arterial pressure, PP = pulse pressure, CO = cardiac output, HR = heart rate, SV = stroke volume, VI = aortic flow velocity index, ACI = aortic flow acceleration index, TAC = total arterial compliance, TFC = thoracic fluid content.
