Conduction Disturbances Located within the His Bundle

Conduction disturbances located within the His bundle.

SUMMARY Four patients are described with different degrees of conduction disturbance within the His bundle. In one patient with a Mobitz type II atrioventricular (A-V) block with normal QRS complexes the blocked atrial beats were followed by a His potential. Since the QRS complexes of the conducted beats were completely normal, the site of the block was thought to be in the distal part of the H...

Problems in the Recognition of Conduction Disturbances in the His Bundle By REINIER

Two cases with conduction disturbances in the His bundle are described. In each it was not possible to obtain both components, H and H', of the "split" His bundle potential at one time from a single bipolar electrode catheter with an interelectrode distance of 10 mm. Initial failure to record the proximal His component (H) led to the incorrect diagnosis of block located within the atrioventricu...
