Incomplete Right Bundle-Branch Block
Incomplete right bundle-branch block (IRBBB) usually is thought to be associated with abnormalities of the peripheral Purkinje system. This paper discusses the results of a study of six dogs from the same family and three nonrelated dogs with congenital IRBBB. Cardiac catheterization data were normal, and no evidence or history of cardiac disease was found before or after death. The depolarizat...

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 ...
متن کاملThe precordial electrocardiogram in incomplete right bundle branch block.
I N 1917 Rothberger and Winterberg’ published an electrocardiographic record which depicts the gradual clearing of a defect in conduction affecting the right branch of the bundle of His. An attempt to cut this structure in the course of an experiment on a dog blocked it only temporarily. Fortunately, one of the tracings taken spanned the period during which the injured bundle gradually recovere...
متن کاملIncomplete right bundle branch block and vital capacity.
Right bundle branch block (RBBB) is occasionally encountered in young persons who lack any other evidence of overt cardiac disease (Hiss and Lamb, 1962; Lancaster, Schechter, and Massing, 1972). The block may be complete or incomplete, the latter being more common. Right bundle branch block has been studied in relation to body weight, obesity, serum cholesterol and glucose levels, and blood pre...
متن کاملThe incomplete left bundle branch block.
(ILBBB) has received scant attention in the literature as an elec-trocardiographic entity, seemingly due to its multiple etiologies and its superficial resemblance to left ventricular preponderance (LVP) ,** and left ventricular is-chemia. In a review of current texts, Fried-berg,1 Lipman and Massie,2 Wolff3 and Levine4 stress the difficulty in electrocardio-graphically differentiating the ILBB...
