Cardiotoxicity in imipramine intoxication: report of one case
Abstract:
Imipramine is the most commonly prescribed tricyclic antidepressant of acute life threatening self-poisoning. We report a 15-month-old boy of accidental poisoning with imipramine, who developed generalized tonic-clonic convulsions and drug-related cardiac conduction abnormalities with PR prolongation, QRS widening, and QTc lengthening. The patient's imipramine level was 1389 ng/ml. The rapid resolution of intraventricular conduction delay and normalization of the QRS-T complexes after gastric lavage, installation of activated charcoal and alkalinization of the blood strongly implicates imipramine intoxication in the etiology of the cardiotoxicity. The patient made a full recovery without neurological sequelae.
