The Brugada syndrome is a rare disease potentially leading to severe arrhythmic events in otherwise healthy subjects.In many patients an Implantable cardiovertor defibrillator (ICD) is implanted to prevent sudden cardiac death. ICD are however associated with potential complications and are not available in all countries.Pharmacological blockade of specific ion channels (Ito) represents a promising therapeutic approach in this syndrome.The 3,4-diaminopyridine (3,4-DAP) is a pharmacological Ito blocker that can be used in humans.The aim of the study is to evaluate the effect of 3,4-DAP on ventricular arrhythmia inducibility in Brugada patients requiring an electrophysiological study for arrhythmic risk stratification.
