Post-operative Brugada electrocardiographic pattern, polymorphic ventricular tachycardia, and sudden death in a child after administration of propofol anaesthesia.

A 9-year-old African-American girl presented with sudden cardiac arrest a few hours after adenotonsillectomy. She received anaesthesia which included propofol during the procedure. Her electrocardiogram (EKG) showed type 1 Brugada pattern, and genetic testing revealed a variant of unknown significance in desmoplakin (DSP) gene. We discuss the association between propofol, Brugada EKG pattern, and malignant ventricular arrhythmias.
