Summary: Brugada syndrome (BrS) is a dynamic RV electromechanical disease where functional abnormalities correlate with the maximal extent of the substrate size; patients with BrS show a reduction in right ventricular ejection fraction and mechanical abnormalities localized at RV outflow tract after ajmaline challenge.

Summary: In this study, a clinical analysis was conducted on 261 patients diagnosed with fever-induced Brugada syndrome (BrS). It was found that patients carrying pathogenic or likely pathogenic (P/LP) SCN5A gene variants were more susceptible to fever-induced BrS at a younger age, especially among Caucasian individuals and females. These patients exhibited significant electrophysiological abnormalities and had a higher incidence of major cardiac events (MCE).

Summary: The study evaluated the long-term prognosis of a large cohort of asymptomatic patients with Brugada ECG pattern. The entire population of asymptomatic patients with BrECG exhibited a relatively low event rate per year, with those having spontaneous type-1 BrECG and positive EPS showing higher risk. Asymptomatic patients with drug-induced-only BrECG had minimal arrhythmic risk, but ongoing follow-up was recommended to detect the appearance of spontaneous type-1 BrECG pattern.

Summary: Brugada syndrome is an arrhythmogenic disease with a higher prevalence and risk in males compared to females. Females with the syndrome are more frequently asymptomatic and older at the time of diagnosis. Sex hormones, particularly testosterone, may play a role in these differences. However, current research on Brugada syndrome focuses mainly on males, lacking gender-related information.

Summary: Brugada Syndrome (BrS) is a genetic arrhythmogenic disorder associated with mutations in genes affecting the sodium channel NaV1.5. This study investigated the involvement of sialylation, a post-translational modification, in BrS. The researchers found significant alterations in gene expression and protein sialylation in BrS patients, which were associated with the clinical phenotype of the disease. Furthermore, protein desialylation was found to reduce sodium current. These findings suggest that dysregulation of sialylation may play a role in BrS and could potentially be used as a biomarker for the disease.

Summary: This study found that 18% of BrS patients exhibited a left axis deviation during provocation testing, which was not explained by terminal conduction slowing in the right ventricular outflow tract but was associated with more proximal conduction slowing. The left axis deviation led to a discordant repolarization, and it remains uncertain whether this has implications for risk stratification.

Summary: Brugada syndrome and early repolarization syndrome are both J-wave syndromes with similar mechanisms of arrhythmogenesis and structural abnormalities. As imaging techniques advance, these syndromes may be reclassified as structural heart diseases or cardiomyopathies.

Summary: Syncope in patients with Brugada syndrome can stem from both benign forms and malignant arrhythmias, making it challenging to differentiate between the two without recording an electrocardiogram during the episode. Thus, a diagnostic and treatment approach is crucial when faced with syncope in Brugada syndrome patients.

Summary: Brugada syndrome is an ion channel disease characterized by a unique ECG pattern and increased risk of cardiac arrhythmias. Although the genetic transmission of this condition is diverse, the SCN5A gene is considered the primary disease-causing gene. Current understanding of the genetic architecture of the disease suggests involvement of polygenic inheritance and a polygenic risk score.

Summary: The 12-lead ECG plays a crucial role in diagnosing Brugada syndrome. A systematic review identified 12 specific ECG features associated with a higher risk of sudden death in BrS patients. A multiparametric risk assessment approach based on these ECG parameters could potentially improve current risk stratification scores and warrants further investigation.

Summary: Brugada syndrome is responsible for about 20% of sudden cardiac deaths in apparently normal hearts, mainly characterized by ventricular arrhythmias. Research has found that delays in activation and repolarization over the right ventricular outflow tract may be the main cause of the typical ECG pattern and arrhythmias. Noninvasive mapping systems may be important for evaluating the arrhythmogenic substrate of Brugada syndrome.

Summary: The diagnostic yield of SCN5A gene testing in paediatric BrS patients is 46%, and having a P/LP variant in SCN5A is associated with a worse arrhythmic prognosis in children with BrS. There is no significant difference in the prognosis of ventricular arrhythmias between paediatric and adult BrS patients.

Summary: Brugada syndrome is an inherited cardiac disorder with a typical ECG pattern and increased risk of arrhythmias and sudden cardiac death. Diagnosis and risk prediction are challenging, but with the rise in asymptomatic patients and family screenings, the incidence is expected to increase.

Summary: Brugada syndrome is a rare hereditary arrhythmia disorder with a distinct ECG pattern. It is correlated with an increased risk of ventricular arrhythmias and sudden cardiac death in young adults. The molecular anomalies in Brugada syndrome result in modifications in excitation wavelength, leading to an increased risk of arrhythmia.
