[Results of a study on the circadian rhythm of catecholamine excretion on normal subjects and those with high excretion levels (author's transl)]. / Ergebnisse einer Kurzzeitstudie über die circadiane Rhythmik bei normaler und erhöhter Katecholaminausscheidung im Urin

The circadian rhythm of the excretion of the catecholamines and some main metabolites is investigated in five normal subjects and two patients with a high excretion. In the normal subjects there are remarkable differences in the amplitudes of the variables. At high catecholamine excretions these differences seem to disappear.
