The 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 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
Y THE TIME the patient with acute myocardial infarction is first examined, his electrocardiogram may already show changes in the RS-T segment alone, in the T wave alone, in the QRS complex alone, or in any combination of the three. Changes in any of these portions of the ventricular complex and particularly in the QRS may not appear for hours or days. Some never show distinctive electrocardiogr...
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...
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...
