Brugada syndrome is still a current clinical problem. What do we know today - a literature review

Abstract

Brugada syndrome (BrS) is a rare congenital arrhythmia syndrome. BrS is characterized by a tendency to syncope, ventricular arrhythmias and sudden cardiac death. These symptoms occur mainly at night and can occur spontaneously or as a result of provocation by, for example, fever, stress or medication. Based on the differences in electrocardiography, three types were distinguished. Genetic studies are being conducted, which have shown a significant defect of the SCN5A gene, which in turn leads to disturbances in the functioning of the sodium channel NaV1.5 has a negative impact on the course of depolarization of myocardial cells. Patients with symptoms of the disease are subjected to implantation of a cardioverter-defibrillator, which protects them against sudden death. Data was obtained from the PubMed and Google Scholar platforms.
