Key result
Doppler-measured ascending aortic mean acceleration is strongly linked to peak velocity in healthy children.
Why the study?
Normal values for Doppler parameters of left ventricular function in healthy children with BSA < 1 m2 were not established.

What are the normal values for Doppler parameters of left ventricular function in healthy children?
Effect estimate: r = 0.75
p-value: p=< 0.0001
This study establishes reference values for Doppler echocardiographic parameters of left ventricular function in healthy children under 10 years old.
Sohn et al. (2001) conducted a cross-sectional in Healthy children (n=63). Pulsed wave Doppler echocardiography was evaluated on Normal values for Doppler parameters of left ventricular function (ascending aortic blood flow velocity) (r = 0.75, p=< 0.0001). Ascending aortic blood flow velocity measured by pulsed wave Doppler echocardiography in healthy children showed mean acceleration was strongly related to peak velocity (r = 0.75, p < 0.0001).
