Reference ranges of filling time and systolic-to-diastolic time index of the left ventricle, right ventricle, and interventricular septum using both spectral and tissue Doppler of fetal heart between 20 and 36  + 6 weeks of gestation

The objective of this study is to determine the reference ranges for filling time (FT) and systolic-to-diastolic time index (SDI) of the left ventricle (LV) by using spectral Doppler, and FT ’ and SDI’ of the LV, right ventricle, and interventricular septum (IVS) by using tissue Doppler of the fetal heart.
