Incomplete left bundle-branch block. A definite electrocardiographic entity.
SUMMARY Rate-dependent intermittent incomplete and complete left bundle-branch block (LBBB) is described in a patient without other evidence of heart disease. Continuous electrocardiographic tracings revealed QRS complexes intermediate in configuration between normal conduction and complete LBBB during the transitional phase from normal to abnormal conduction. This provided an opportunity to st...
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...
متن کاملIncomplete 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 ...
متن کاملIncomplete 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...
متن کاملLeft Bundle Branch Block
Coronary angiography, cine left ventriculography, and the cardiovascular hemodynamics of 24 patients with left bundle branch block were studied. Seven patients were found to have significant coronary artery disease, always severe. Five had cardiomyopathy and seven had valvular disease. Only those with coronary artery disease or cardiomyopathy had abnormal left ventricular contraction patterns. ...
