Population
30 children aged from 5 months to 16 years (mean 4.8 +/- 4.4 years)
Comparison
Dobutamine infusion (5 microg/kg per minute) vs Basal values (before dobutamine infusion)

Age-adjusted norms may be needed for pediatric dobutamine stress testing; leaves open mechanisms and thresholds for clinical use.
Does dobutamine infusion alter coronary flow velocity response and left ventricular functional reserve in children?
Responses of left ventricular contractility and coronary flow to low-dose dobutamine are less sensitive in younger children and increase with age.
Yasuoka et al. (2001) studied this question.
