OBJECTIVE To determine the prevalence of the Brugada sign (right bundle branch block with ST elevation in V1-V3) in idiopathic ventricular fibrillation and in an age matched healthy population. DESIGN ECGs from 39 consecutive patients with idiopathic ventricular fibrillation and 592 healthy controls were reviewed. They were classified as definite, questionable, and no Brugada sign (according ...

Brugada syndrome is increasingly recognized as a clinical syndrome world wide. We report a case with a new SCN5A mutation. As the awareness of this disease entity increases more cases will probably be found.

BACKGROUND Many subjects in community have non-type 1 Brugada pattern ECG with atypical symptoms, relevance of which is not clear. Provocative tests to unmask type 1 Brugada pattern in these patients would help in diagnosing Brugada Syndrome. However sensitivity and specificity of provocating drugs are variable. METHODS We studied 29 patients referred to our institute with clinical presentati...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) and Brugada syndrome are distinct clinical entities which diagnostic criteria exclude their coexistence in individual patients. ARVC is a myocardial disorder characterized by fibro-fatty replacement of the myocardium and ventricular arrhythmias. In contrast, the Brugada syndrome has long been considered a functional cardiac disorder: no gro...

We identified a patient with the Brugada syndrome and frequent episodes of the traumatic syncope. This patient presented with alternating ST-segment elevation in the right precordial and the high lateral leads. The signal-averaged ECG was positive for the late potentials and electrophysiology study revealed no inducible supraventricular or ventricular tachycardias. Because of the frequent traum...

Brugada syndrome is associated with sudden cardiac death in young patients. Currently guidelines recommend the use of implantable cardioverter-defibrillator (ICD) in high-risk patients to prevent sudden cardiac death and adjunctive therapy with quinidine in those who have recurrent ventricular tachyarrhythmias to prevent electrical storm. Nevertheless, not all patients respond to quinidine, and...

We present a Brugada syndrome patient who suffered an aborted sudden death. The ajmaline test (1 mg/kg body weight) induced accentuated alternans ST-segment elevation in V1-V2 without ventricular arrhythmias. It could represent silent ischaemia not detected before, failure of myocardial regions to repolarize in alternate beats due to transmural dispersion of conduction and refractoriness in the...

BACKGROUND Elevated plasma testosterone levels are thought to play a role in the male preponderance of cases of Brugada syndrome (BS) and the development of prostate cancer. METHODS AND RESULTS The 34 Brugada-like electrocardiogram (ECG) cases were identified among 2,681 male survivors of the atomic bomb who had undergone at least 1 biennial health examination between July 1958 and December 1...
