Sex 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 کاملThe 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 کاملThe Frontal Plane Vectorcardiogram
The mid-to-late part of the frontal plane QRS loop (Frank lead system) of 150 consecutive subjects with an old inferior myocardial infarction was analyzed. During the acute episode all cases had to satisfy Myers' classical ECG criteria for the diagnosis. The vectorcardiogram was recorded months to years later. As a result of this analysis and in order to prevent overlap with values found in 450...
متن کاملThe spatial vectorcardiogram in diagnosis.
THE spatial vectorcardiogram is an approximate model of the moment-to-moment changes in direction and magnitude of the unbalanced electrical activity of the heart in three dimensions. In practice it is recorded from the surface of the human thorax through specially placed electrodes, so the information it records is essentially similar to that recorded by scalar (surface) electrocardiography. A...
متن کاملThe vectorcardiogram of cardiac infarction.
A simple method of drawing the three-plane projection of the spatial vectorcardiogram has been described (Shillingford and Brigden, 1951). A series of normal vectorcardiograms were studied and found to have certain constant characteristics that were comparable with the results obtained by electronic methods. In this paper we report the vectorcardiographic findings of extensive cardiac infarctio...
