We report the results of a prospective study of pulmonary venous (PV) flow Doppler velocities in 68 normal children. We sought to establish the normal PV flow velocities in the broad pediatric population, compare these velocities to heart rate and age. In normal children, there is a wide range of PV flow velocities, most of which correlate with age and heart rate. However, the PV flow velocities and their durations do not distinguish the age groups. The peak velocity of systolic forward flow and atrial reversal flow in the pulmonary vein were independent of heart rate. The PV flow peak systolic velocity showed a weak correlation with the velocity of the mitral inflow early wave. However, the velocity of atrial reversal flow showed no correlation with the mitral inflow A velocity (late wave), which is generated by the same force of atrial contraction.
我们报告了一项对68名正常儿童肺静脉（PV）血流多普勒速度的前瞻性研究结果。我们试图确定广大儿童群体中的正常PV血流速度，并将这些速度与心率和年龄进行比较。在正常儿童中，PV血流速度范围很广，其中大多数与年龄和心率相关。然而，PV血流速度及其持续时间并不能区分年龄组。肺静脉收缩期正向血流和心房逆向血流的峰值速度与心率无关。PV血流收缩期峰值速度与二尖瓣流入早期波速度呈弱相关。然而，心房逆向血流速度与由相同心房收缩力产生的二尖瓣流入A速度（晚期波）无相关性。
