Abstract

The Brugada syndrome (BrS) is an inherited disorder associated with increased risk of sudden cardiac death (SCD). Despite the rare occurrence of BrS, timely diagnosis and risk stratification are important tasks today. The presence of syncope of arrhythmic origin in conjunction with a spontaneous ECG pattern of BrS type 1 is a reliable indicator of a poor prognosis. Conversely, in the group with non-arrhythmic syncope, there is no increased risk of life-threatening ventricular tachyarrhythmias. However, the etiology of syncope is difficult to determine in 30% of cases. It is known that data obtained using implantable loop recorders can change therapy strategy in 20–36% of patients with BrS with unexplained syncope, what is a factor in stratifying the cardiac risk of sudden death in this group of patients. The article provides a brief overview of the medical literature and illustrates instances of the diagnosis of syncope in a patient with BrS. Modern approaches of diagnosis and treatment of BrS including catheter ablation and gene therapy are discussed. The clinical characteristics of the disease and the data of laboratory and instrumental studies of presented case are given.
