Vectorcardiogram in Right Bundle Branch Block with Frank's System

The spatial vectorcardiogram in right bundle branch block.

Electrocardiogram and Vectorcardiogram in Right Ventricular Hypertrophy and Right Bundle - Branch Block

Wit/i the collaboration of Charles A. Bertrand, M.D., and Frederick R. Mugler, M.D. Electrocardiographic and vectorcardiographic studies on normal subjects and patients with heart disease suggest that criteria for the diagnosis of right ventricular hypertrophy can be improved and simplified. This report proposes new criteria for the electrocardiographic diagnosis of right ventricular hypertroph...

The vectorcardiogram in right bundle branch block: correlation with cardiac failure and pulmonary disease.

Frank vectorcardiograms (VCG) and clinical records of 243 patients with right bundle branch block (RBBB) were compared. The patients were classified into three categories on the basis of VCG criteria. The first category included 100 patients with a normal frontal axis, and the second category included 44 patients with concomitant left anterior hemiblock. The third category consisted of 99 patie...

The spatial vectorcardiogram in left bundle branch block.

A method of vectorcardiography, in which the projections of the spatial veetorcardiogrami in various planes of an equilateral tetrahedron reference system are recorded, has been applied to the study of left bundle branch block. Results suggest that the method employed may provide information relative to the state of the miyocar(liutim and the extent of myocardial lesions which is not evident fr...

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...
