aortic flow

A serial study of intracranial perfusion and ascending aortic flow in newborns

新生儿颅内灌注与升主动脉血流的动态研究

There were high correlations between RE-measured pulse pressure arising time and DE-derived aortic flow acceleration time , and between RE-measured and DE-derived left ventricular ejection time ;

脉图脉压上升时间和左室射血时间分别与多普勒测量的主动脉血流加速时间和左室射血时间相关；

Following this assumption with customized computer software the aortic flow profile was digitized and converted to 4V 2 curve whose maximum value of the first derivative is termed as max ( dk / dt ) .

应用特制计算机软件将主动脉血流速度曲线转化为4V2曲线，该曲线的一级导数峰值即为Max（dk／dt）。
