Bilateral bundle branch block.

Bilateral Bundle-Branch Block

The electrocardiograms and salient clinical features of seven patients with electrocardiographic evidence of various types of bilateral bundle-branch block (BBBB) have been presented. When the complexes change in form and the P-R interval varies, the mechanisms are usually best interpreted by using the concepts of first degree, second degree, and third degree bundle-branch block with or without...

Paroxysmal Heart Block in Bundle Branch Block.

When a patient is suspected of having Stokes-Adams disease the electrocardiogram is of critical importance, particularly in respect of the auriculo-ventricular (A-V) conduction time. Should this not be prolonged, the possibility of paroxysmal heart block remains, although the diagnosis of Stokes-Adams disease is uncertain without some degree of heart block recorded graphically. It is not known ...

Prolonged Atrio-Ventricular Block Following Scorpion Bite: A Case Report

This report describes a 55-year-old woman in whom yellow scorpion sting resulted in the development of Mobitz type 1 and transient complete heart blocks unresponsive to atropine administration.  It might be concluded that although autonomic involvement including parasympathetic overactivity is present in such cases, other factors such as toxic damage to the cardiac conduction system may play a ...
