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 ...

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.

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.

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.

Prognosis in bundle branch block
American Heart Journal, 1950Abstract In A previous communication the factors influencing the survival time in right bundle branch block were analyzed. The purpose of this paper is to analyze in a similar fashion a consecutive series of 555 patients showing the electrocardiographic pattern of left bundle branch block.

Bundle Branch Blocks and Hemiblocks
2016The conduction system beyond the atrioventricular (AV) node normally runs in the interventricular septum. The normal route for electrical depolarization is through the AV node into the bundle of His, which bifurcates into the right bundle branch and the left bundle branch.
