چکیده

Disturbance Underlies the Electrocardiographic Pattern of the So-Called Brugada Syndrome To the Editor: It is a privilege to acknowledge the scientific accuracy of Dr Wilde and coworkers who admitted that some depolarization abnormalities underlie the so-called Brugada syndrome.1 In a previous article,2 Dr Wilde wrote, “Both theoretical considerations and in vivo experiments support the idea that heterogeneity of repolarization across the wall of the RV outflow tract (RVOT) contribute to the ECG patterns and the genesis of arrhythmias in the Brugada syndrome” (p 669). This recent admission gives further credit to our observation on a patient with the syndrome 20 years ago.3,4 This stillhealthy patient, who can be seen on page 70 of http:// digilander.libero.it/martini_syndrome/, had a documented QRS delay at the right ventricular outflow tract.3 Prolonged PR and HV intervals, left axis deviation, and late potentials both spontaneously and after flecainide were all reported in this syndrome.5 All are consistent with organic disease of the conduction system as documented at necropsy.3

Masquerading bundle branch block obscuring the diagnosis of Brugada syndrome: an electrocardiographic and vectorcardiographic study

We describe the induction of a masquerading bundle branch block in two patients with Brugada syndrome following the administration of Ajmaline. The development of this conduction disturbance prevented the correct electrocardiographic diagnosis. However, the simultaneously obtained vectocardiogram identified both the Brugada pattern and the masquerading bundle branch block.

Abstract Background: Brugada Syndrome (BS) is an inherited ion channelopathy characterized by an electrocardiographic (ECG) pattern of a coved type ST segment elevation in right precordial leads with or without right bundle branch block. Case Presentation: A 23-year old male presented with right lower quadrant abdominal pain. Further evaluation revealed a diagnosis of acute appendicitis. The ...

New Electrocardiographic Features in Brugada Syndrome

Brugada syndrome is a genetically determined familial disease with autosomal dominant transmission and variable penetrance, conferring a predisposition to sudden cardiac death due to ventricular arrhythmias. The syndrome is characterized by a typical electrocardiographic pattern in the right precordial leads. This article will focus on the new electrocardiographic features recently agreed on by...

Genetic testing in Brugada syndrome.

Brugada syndrome (BrS) is a hereditary arrhythmic disorder associated with a right ventricular conduction delay and ST-segment elevation in the right precordial leads and syncope and sudden death due to ventricular fibrillation (1). The type 1 Brugada electrocardiographic ECG pattern (coved ST-segment elevations in leads V1 to V3) is a ynamic finding that may be present at baseline or may ecome...
