title: Cardiotoxicity and late onset seizures with citalopram overdose.
abstract: A 31-year-old man ingested 400 mg of citalopram (Celexa) after an argument with his parents and girlfriend 13 h before presentation. Paramedics witnessed the patient having a generalized clonic seizure. The electrocardiogram (EKG) revealed a wide QRS complex, prolongation of the QTc interval, and left bundle branch pattern. He was treated with sodium bicarbonate with resolution of these changes. The patient was continued on a sodium bicarbonate infusion and demonstrated no further EKG abnormalities. Sodium bicarbonate should be considered as a treatment modality in patients with EKG abnormalities of prolongation of QRS or QTc interval after citalopram overdose.
