Studies 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 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 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...
