Brugada syndrome can be unmasked by several conditions including a febrile state, marked leukocytosis, and electrolyte disturbances. Herein, we describe a 62-year-old man with cholangiocarcinoma in the first reported case of Brugada syndrome onset following photodynamic therapy.

This review deals with the clinical, basic and genetic aspects of a recently highlighted form of idiopathic ventricular fibrillation known as the Brugada syndrome. Our primary objective in this review is to identify the full scope of the syndrome and attempt to correlate the electrocardiographic manifestations of the Brugada syndrome with cellular and ionic heterogeneity known to exist within t...

Introduction. Brugada syndrome is characterized by a disruption of heart's normal rhythm. It is an autosomal dominant disease due to a mutation of SNC5A gene. Its prevalence is low all over the world, but it is a lethal disease. Sudden cardiac death is the result of phenotypic manifestation of Brugada syndrome. Among asymptomatic Brugada patients, arrhythmia could be provoked by physical activi...

Objective/Background: Patients with the Brugada syndrome who experience syncope or aborted sudden death are at high risk for recurrent lethal arrhythmias. However, the prognosis and the therapeutic approaches in asymptomatic individuals with a Brugada-type ECG (asymptomatic Brugada syndrome) are controversial. Methods/ Results: We genetically screened 30 asymptomatic probands (male 29, female 1...

(I-MIBG) Imaging in Brugada Syndrome To the Editor: We read with interest a recent article in Circulation by Wichter et al1 on cardiac autonomic dysfunction in Brugada syndrome. The authors demonstrated that regionally reduced iodine-123-metaiodobenzylguanidine (I-MIBG) uptake in the inferior and septal left ventricular wall was present in 8 (47%) of 17 patients with Brugada syndrome but in non...

First presented by Brugada and Brugada in 1992, Brugada Syndrome (BrS) is a primary electrical disease of the heart that causes sudden cardiac death or life-threatening ventricular arrhythmias. This disease is hereditary autosomic dominant transmitted and genetically determined. The syndrome has been linked to mutations in SCN5A, the gene encoding for the a-subunit of the sodium channel. Electr...

OBJECTIVE The aim of this study was to perform quantitative signal analysis of high-resolution body surface potential mapping (BSPM) recordings to assess its usefulness for the electrocardiographic characterization of patients with Brugada syndrome. The diagnostic value of the QRS integral and of the gradient of the ST segment have not been elucidated in Brugada syndrome. METHODS In 27 subjec...

introduction brugada syndrome (brs) is an autosomal-dominant inherited cardiac arrhythmia that occurs due to sodium channelopathy and increases sudden cardiac death due to episodes of polymorphic ventricular tachyarrhythmia. it is characterized by st-segment elevation in the right precordial leads and right bundle branch block (rbbb) pattern. we herewith present a case of brugada syndrome with ...

BACKGROUND Mutations in the cardiac sodium (Na) channel gene (SCN5A) give rise to the congenital long-QT syndrome (LQT3) and the Brugada syndrome. Na channel blockade by antiarrhythmic drugs improves the QT interval prolongation in LQT3 but worsens the Brugada syndrome ST-segment elevation. Although Na channel blockade has been proposed as a treatment for LQT3, flecainide also evokes "Brugada-l...
