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 …
Objective 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. Study Design This prospective and cross-sectional study included
360 low-risk singleton pregnancies between 20 and 36+ 6 weeks of gestation. The
SDI/SDI'is the sum of the ejection time, isovolumic contraction time, and isovolumic …
