| Abstract: | The Doppler flow spectra of valvular orifices (MV, TV, AV and PV) in 100 normal persons were measured by ASU-010 Doppler echocardiography system. The main parameters were reported. Peak flow velocity (PFV) of various valvular orifices was shown as follows. AVO 92-101 cm/s, MVO 75-96 cm/s, PVO 78-84 cm/s, TVO 55-73 cm/s. Average accelarative velocity (AAV) and descending velocity (ADV) of aorta valvular orifice were higher than that of valvular orifice of pulmonary artery, and the above parameters in the group under 15 years of age were higher than the group over 15. It may be suggested that the blood flow velocity of the left ventricle was higher than that of the right ventricle and the hemocynamic changes of the children were greater than those of the adults. ADVE, E/A, which reflect the diastolic function of left ventricle, decrease gradually with age. |
