Figure 3 Specific (3H)-noradrenaline uptake1 in right atrial (RA) slices obtained from 4 children of group A (A) (2 males and 2 females; mean age 5 ± 2 years) and 5 elderly patients of group B (B) (5 males; mean age 59 ± 5 years) (New York Heart Association functional class 1.80 ± 0.20). Ordinate: specific (3H)-noradrenaline uptake1 (in the presence of 40 µmol/l corticosterone) in pmol (3H)-noradrenaline/mg tissue per 15 min; abscissa: (3H)-noradrenaline concentrations in nmol/l. Data are presented as the mean value ± SEM. **p < 0.01 and ***p < 0.001 vs. group A.
