The concept of 'masquerading' bundle-branch block
S Afr Med J.
.
Abstract
The electrocardiographic features and genesis of so-called masquerading' bundle-branch block are presented. The phenomenon is essentially a right bundle-branch block with left anterior hemiblock, with further modifications of the initial and terminal QRS vectors, so that the standard leads, and at times the left precordial leads, resemble left bundle-branch block.
