[Measurement of aortic flow indices by Doppler echocardiography for the determination of systolic function in infants and children].

Aortic blood flow velocity indexes measured by Doppler echocardiography to assess systolic function in infants and children. The obtained M-mode parameters were correlated with Doppler findings. We found the closest correlation between lin. EF and peak flow velocity integral (r = 0.83 p less than 0.001) Echocardiography completed by Doppler studies proved to be a safe noninvasive method not only estimating left ventricle dysfunction but in assessment the changes in the follow up too.
