Abstract:
Objective To investigate the variational regularity of cardiac function in the early term infants.Methods Dynamic change of cardiac function was monitored by color Doppler echocardiography from the 1st day to 7th day after birth in the term infants,the indexes including blood-pumping function and flow rate of all valve orifices.Results Left ventricular ejection fraction appeared to be no difference during the first 3 days after birth.it gradually increased on the 5th and 1st days,while it was obviously higher on the 6th and 7th days than that of the first 3 days(P0.05).Conclusions Blood-pumping function of left ventricle gradually increases with days in the 1st week after birth.it attains to the maximum on the 6th and 7th days.The AV and PV gradually increase in the 1st week,too.Diastolic function of right ventricle is mature step by step.
