Intravenous lipid emulsion in wide complex arrhythmia with alternating bundle branch block pattern from cocaine overdose

Abstract

We describe the management of a young patient who had experienced a cocaine overdose. The patient presented with altered mental status and seizures and subsequently developed a wide complex arrhythmia with a rare alternating bundle branch block pattern. Intravenous lipid emulsion was administered following initial resuscitation and endotracheal intubation, because conservative methods of treating the persistent cardiac arrhythmias failed.
