The measurement for each cardiac Doppler measurement was expressed as a Z score (difference between observed and expected values divided by the fitted SD corrected for gestational age) and percentile. Analysis included calculation of gestation-specific SDs. Regression equations are provided for the cardiac inflow and outflow tracts. This study establishes reference ranges for fetal cardiac Doppler measurements and heart rate between 13 to 36weeks' gestation that may be useful in clinical practice. This study establishes reference range
