BACKGROUND: The characteristic ECG of Brugada syndrome (BS) can be masked by complete right bundle-branch block (CRBBB) and exposed by resolution of the block or pharmacological or pacing maneuvers.METHODS AND RESULTS: The study consisted of 11 patients who had BS and CRBBB. BS was diagnosed before
A 69-year-old man without structural heart disease was admitted for syncope. His electrocardiogram displayed complete right bundle branch (CRBBB). A coved type ST elevation was observed with transient normalization of CRBBB giving rise to a normal QRS. These findings suggest that Brugada syndrome ca

AIMS: Previous studies have reported right bundle branch block in Brugada syndrome. Subsequent analysis of electrocardiograms (ECGs) found one-third of cases classified as right bundle branch block did not meet criteria of a wide final S wave in the left leads. We aimed to study the role of the vect
