Mean differences between hemodynamic variables measured by impedance cardiography at baseline and 90 seconds after passive leg raising during the second half of pregnancy.

Data are presented as mean values for the difference (delta-values) between the measurements recorded at PLR and baseline (95% confidence intervals). p <0.05 was considered as significant. GA, gestational age; SV, stroke volume (ml); CO, cardiac output (L/min); cardiac index (L/min/m2); HR, heart rate (beats/min); BPS, systolic blood pressure (mm Hg); BPD, diastolic blood pressure (mm Hg); MAP, mean arterial pressure (mm Hg); SVR, systemic vascular resistance (dyne s/cm5); SVRI, systemic vascular resistance index (dyne s m2/cm5); TFC, thoracic fluid content (1/kOhm); ACI, acceleration index (1/100 s2); LCWI, left ventricular work index (Kg m/m2); PEP, pre-ejection period (ms); LVET, left ventricular ejection time (ms); VI, velocity index (1/1000s) and STR, systolic time ratio (%).
