Abstract

Abstract Background Brugada syndrome is a cardiac disorder associated with a high risk of sudden cardiac death, especially in young subjects. The incidence and prevalence are likely underestimated. The diagnosis is based on a characteristic electrocardiography (ECG) pattern. The most commonly performed confirmatory test in cases of equivocal ECG is the intravenous ajmaline challenge. Although relatively safe, it carries the risk of ventricular arrhythmias that could potentially degenerate into a refractory electrical storm. Case report A 27-year-old man developed sustained ventricular fibrillation after ajmaline challenge. He was rescued on extracorporeal life support after 108min of cardiopulmonary resuscitation. Extracorporeal life support allowed recovery of spontaneous circulation and resulted in a positive neurological outcome. <Learning objective: This case is an example of how extracorporeal life support was instituted after prolonged and unsuccessful cardiopulmonary resuscitation resulting in a positive central neurological outcome.>
