title: [Repolarisation disturbances in the ECG under antidepressant drugs. A comparison of two drugs, differing in chemical structure and pharmacological profile (author's transl)].
abstract: In connection with clinical drug trials we compared the ECG-recordings during application of two different antidepressants. Tandamine (AY 23946) is a tricyclic drug with main effects on the norepinephrine reuptake, Fluvoxamine (DU 23 000) a nontricyclic antidepressant with a selective effect on the serotonin reuptake. No differences were observed regarding both frequency and patterns of the repolarisation disturbances. Thus, it appears that the chemical structure of the drug is not responsible for the "typical" form of the repolarisation disturbances. We further hypothesize that toxic effects and regulatory mechanisms of the cardiovascular system, caused by changes in norepinephrine and 5-hydroxytryptamine levels may be responsible for the areforementioned ECG aberrations.
