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.
متن کاملIncomplete Right Bundle-Branch Block
Incomplete right bundle-branch block (IRBBB) usually is thought to be associated with abnormalities of the peripheral Purkinje system. This paper discusses the results of a study of six dogs from the same family and three nonrelated dogs with congenital IRBBB. Cardiac catheterization data were normal, and no evidence or history of cardiac disease was found before or after death. The depolarizat...
متن کامل[Proceedings: Vectorcardiographic study of right bundle-branch block with left axis deviation].
The electrocardiographic pattern of right bundlebranch block in the precordial leads associated with left axis deviation in the limb leads has been noted by others. Wilson, Johnston, and Barker (1934) were the first to describe a small wide R and S wave in lead I, with a wide and deep S wave in leads II and III, and a typical RBBB pattern in the praecordial leads. Recently, Lepeschkin (1964) re...
متن کاملRight Bundle - Branch Block and Left Anterior
Right bundle-branch block occurred in 42.8% and left anterior hemiblock in 35% of 14 patients after surgical replacement of the tricuspid valve. The combination of RBBB with left anterior hemiblock is caused by injury to the branching portion of the bundle of His or more likely, by a lesion involving the pseudobifurcation. This study provides further proof that left anterior hemiblock may be pr...
متن کاملRight bundle branch block and cardiac infarction.
It is the object of this paper to investigate the modifications of the electrocardiographic pattern of cardiac infarction caused by the simultaneous presence of right bundle branch block, and to describe the cardiographic signs on which the diagnosis of infarction can be made in the presence. of right branch block. The cardiogram of right branch block shows added changes characteristic of infar...
