Patients with repaired tetralogy of Fallot are at risk of ventricular tachycardia (VT) and sudden cardiac death. Historically, risk stratification electrophysiologic studies involved programmed ventricular stimulation with VT induction guiding implantable cardioverter-defibrillator (ICD) implantation or VT ablation.

Brugada syndrome is thought to account for about one fourth of sudden cardiac deaths in individuals with structurally normal heart. This is mainly to account for the individual variation in anatomical location of right ventricular outflow tract, the main location of electrophysiological abnormalities in Brugada syndrome.
