The increasing number of ion channelopathies discovered in the heart, with fatal consequences, implies that the specialists involved in the management of these patients must strive to reach a better understanding of basic cardiac electrophysiology. In the Brugada syndrome, up to six genotypes have already been described with affectations in the sodium, calcium and potassium (Ito type) channels. In all cases there is a typical electrocardiogram which shows right precordial leads due to the transmural dispersion of repolarization, more pronounced in the region of the outflow tract of the right ventricle. The disease may be asymptomatic or have sudden death as its first manifestation. The implantable defibrillator is considered the most effective treatment, but it can be combined with quinidine to space the shocks and abort electrical storms.
