The Vectorcardiogram in Normal Children.
The evolution of the vectorcardiogram obtained with the Frank lead system (Frank, 1956) from normal infants was reported in a previous publication (Namin et al., 1964). It was based on a study of 216 vectorcardiograms on 107 infants. To establish a baseline for the vectorcardiographic recognition of ventricular overwork patterns in children, the vectorcardiograms of a group of normal older chil...
متن کاملStudies of the spatial vectorcardiogram in normal man.
The spatial vectorcardiograms of 75 normal subjects have been studied and some features of these records are described. The QRS st and T st-loops were found to have only two basic spatial configurations but with a variety of orientations thus giving widely different planar projections and in part accounting for the wide range of normal electrocardiograms. The significance of this and other find...
متن کاملSex differences in the vectorcardiogram.
In a study of 101 normal men and 102 normal women (mean age, 42.5 and 42.6 years, respectively), significant sex differences were observed in 43 of 64 vectorial items analyzed (initial 0.02-sec and 0.025-sec vectors, maximal QRS and T vectors, terminal 0.02-sec vectors in frontal, horizontal left sagittal planes; Q, R, S, and T deflections in Frank's X, Y, and Z leads). The initial QRS vectors ...
متن کاملElectrocardiogram and vectorcardiogram in Turner phenotype with normal chromosomes and pulmonary stenosis.
Electrocardiograms and vectorcardiograms from 7 boys with the ' Ullrich-Turner phenotype', pulmonary stenosis, and normal chromosomes were systematically compared with recordings from 37 unselected patients with uncomplicated pulmonary stenosis. The 7 patients had a highly characteristic QRS pattern which differed greatly from that of the control group. The frontal plane QRS loop was almost com...
متن کاملThe Frank vectorcardiogram in normal men. Norms derived from visual and manual measurement of 300 records.
Broad clinical application of vectorcardiography has been limited by the lack of a single, widely accepted recording system and the paucity of firmly established diagnostic norms. Most clinical reports and texts, therefore, have used the vectorcardiogram primarily for vivid pictorial display of typical abnormalities. A recent co-operative study, in which interpretation of the vectorcardiogram b...
