[Hemodynamic and electrocardiographic effects caused by intravenous infusion of a tricyclic antidepressive agent dibenzepin].
The cardiovascular (blood pressure, heart rate, central venous pressure) and ECG changes caused by dibenzepine-infusion (720 mg/day for 48 hours) have been assessed. Mean blood pressure and heart rate did not show significant changes. In some patients, however, distinct changes in both variables were observed. Central venous pressure was not affected. The infusion elicited changes in the repolarisation phase of the ECG: it did not, however, alter either the automaticity or the conductivity of the heart. These results were obtained in 40 depressive patients, whose general conditions and cardiovascular state were excellent and must not be extrapolated for cardiopathic patients. The risks inherent in this therapeutic approach are discussed.
