Heart Sounds in Bundle Branch Block

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 ...

prevalence of left bundle branch block & congestive heart failure

background: many factors influence the prognosis of patients with (chf), among these; more attention has been focused on the role of left bundle branch block (lbbb).  the present study was performed to find out the prevalence of chf in lbbb patients. methods: in this cross-sectional study, 246 were diagnosed consecutive patients with lbbb pattern in ecg during july 2004 until october 2006 at im...

His Bundle electrogram in bundle-branch block.

SUMMARY Because a great majority of patients with chronic complete heart block have bilateral bundle-branch lesions, it becomes important to recognize earlier degrees of bilateral bundle-branch block. The H-V interval in the His bundle electrogram during unilateral bundle-branch block reflects the conduction primarily through the contralateral bundle branch, and thus the His bundle electrogram ...

Incomplete Bundle Branch Block.

Lewis (1925) stated that delay in the passage of the impulse down a bundle branch could alter materially the form of the electrocardiogram. Wilson (1940) defined incomplete bundle branch block as due to a conduction defect that merely retards the passage of the impulse through one of the main bundle branches, and stated that it gives rise to electrocardiograms which are " transitional, both as ...
