title: [Long QT syndrome and Brugada syndrome. Drugs, ablation or ICD?].
abstract: Long QT syndrome and Brugada syndrome are potentially fatal inherited arrhythmogenic diseases. Thanks to the contribution of molecular genetics, the genetic bases, pathogenesis, and genotype-phenotype correlation of both diseases have been progressively unveiled and shown to have an extremely high degree of genetic heterogeneity. The clinical manifestation of the diseases is also highly variable. Symptomatic patients experience ventricular tachyarrhythmias which may lead to recurrent syncope and/or sudden cardiac death. In long QT syndrome patients with syncope, therapy with beta-blockers has proven effective. When, despite beta-blocker treatment, arrhythmia-related symptoms continue to occur, an implantable cardioverter defibrillator is indicated. Such a device should also be implanted in resuscitated patients. In symptomatic patients with Brugada syndrome, the implantable cardioverter defibrillator is the only life-saving option. In asymptomatic patients with a Brugada ECG pattern, risk stratification has become of utmost importance in order to discover which patients really need definitive treatment.
