Abstract 1. 1. An electrocardiographic diagnosis of bilateral bundle branch block can be made in rare instances in which conduction in the branches is not completely interrupted and the degree of block in one of the branches is less than in the other on some occasions and greater on others; this allows the patterns of right and left bundle branch

Prognosis in Bundle Branch Block
Annual Review of Medicine, 1981Chronic bundle branch block is common and is a marker for associated heart disease. In the asymptomatic patient no diagnostic studies or treatment are required. In the patient with symptoms suggestive of a bradyarrhythmia, attempts to document complete heart block should be made and if this rhythm is demonstrated a permanent pacemaker should be ...

Abstract A description is given of a mother who died at the age of 35 years, and of 4 young siblings, all of whom revealed right bundle branch block as an isolated finding.

Left bundle branch pacing in alternating bundle branch block
Journal of Electrocardiology, 2023We present a case of symptomatic intermittent AV block showing during monitorization alternating bundle branch block. Presuming a high need of pacing, conduction system pacing was considered a more physiological alternative in this patient. Left bundle branch pacing restored a stable atrioventricular synchrony with a paced QRS complex similar to the ...

Development of bundle branch block
The American Journal of Cardiology, 1964Abstract Thirty patients were observed before and after the onset of bundle branch block; right-sided conduction defects developed in 15 and left-sided in 15. In 22 patients the appearance of bundle branch block was associated with salient cardiac symptoms; in 8 the conduction defect developed silently.

Left bundle-branch block is ventricular excitation that is prolonged 0.12 second or more. It creates a specific pattern on vectorcardiogram and electrocardiogram, but changes in standardization are often needed to bring out detail.

The term bundle branch block (BBB) implies a conduction disturbance in one of the two main branches of the His bundle, resulting in delayed activation of either the right ventricle or the left one. The right bundle branch being thinner and longer than the left bundle is more vulnerable to small, focal, fibrotic or inflammatory lesions.

BUNDLE BRANCH BLOCK AND ARBORIZATION BLOCK
Archives of Internal Medicine, 1920For the first few years after the introduction of the string galvanometer into clinical medicine, electrocardiographers devoted most of their attention to the analysis of the cardiac irregularies. This field has been so extensively cultivated that it is approaching exhaustion, and there is an increasing tendency to turn to the significance of ...

Expert Review of Cardiovascular Therapy, 2013
The so-called 'masquerading' type of right bundle branch block is caused by the simultaneous presence of a high-degree left anterior fascicular block often accompanied with severe left ventricular enlargement and/or fibrotic block in the anterolateral wall of the left ventricle.
