[Left versus right ventricular Tei index for evaluating third-trimester fetal cardiac function in pregnancy-induced hypertension syndrome].

Objective: To investigate the value of Tei index and the sensitivity of left versus right ventricular Tei index in evaluating the fetal cardiac function in pregnancy-induced hypertension syndrome in the third trimester.

Methods: Fetal echocardiograms were performed in 30 women with pregnancy-induced hypertension (PIH) syndrome and 55 with normal pregnancy of the third trimester. Tei index was obtained by calculating the ratio of the isovolumic time (isovolumic contraction and relaxation time) to the ejection time of the left and right ventricle.
