An unusual bundle-branch block
Journal of Electrocardiology, 2006We report a case of right bundle-branch block (RBBB) showing a QRS configuration typical for left bundle-branch block (LBBB) in leads V(5) and V(6). The QRS axis was at +90 degrees, and the QRS duration was 0.14 second. There were wide S waves in leads I and aVL, suggesting at first glance an RBBB, but the QRS morphology in the inferior leads ...

BENIGN BUNDLE BRANCH BLOCK [PDF]
Archives of Internal Medicine, 1952 THE LOCALIZATION of block in the main branches of the bundle of His was clarified by the studies of Wilson and his co-workers.1In this regard precordial electrocardiography proved to be of great value. The clinical significance of these findings, however, has been confusing, and it is well known that right or left bundle branch block is commonly ...

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

Alternating bundle branch block
Journal of Electrocardiology, 1980Mechanisms postulated for alternating bundle branch block are incomplete- and cycle-length-dependent-block in both the right and left bundle branches. A patient with severe longstanding cardiac conduction disease who developed alternating bundle branch block during treatment for advanced ischemic heart disease and malignant ventricular arrhythmia is ...

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 ...

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.
