Abstract:
Objective:To investigate the values of detecting cardiac function in fetal distress by Tei index.Methods:Study consisted of 32 cases of fetal distress and 80 matched normal subjects.We recorded the Doppler sample volume at mitral valve in the cardiac four-chamber view of the heart.Respectively,population below and above the aortic valve.Mitral A peak measured E peak to the beginning of the end of time a,aortic ejection time b,measured for 2~3 cycles,then chosing the average.According to the formula ICT + IRT/ET = a-b/b,we caculated the Tei index.Results:It showed Tei index of cases the fetal distress significantly larger than normal fetuses(P
