The Frontal Plane Vectorcardiogram
نویسنده
چکیده
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 normal control subjects, four VCG criteria are proposed for this diagnosis. The VCGs of 75 of the 150 patients fulfilled one or more of the four VCG criteria. The ECG, done at the time of VCG, satisfied Myers' or Goldberger's criteria or both criteria in 33 of these 75 patients, and an additional 24 of the 150 fulfilled either

I N THE study of spatial vectorcardiography in this laboratory it has been the practice to construct wire models of the spatial vectorcardiogram from its frontal and sagittal projections which are presented on two cathode-ray tubes.'' 2 These three-dimensional models seemed necessary to facilitate visualization of the spatial characteristics of the vectorcardiogram, but their construction entai...
متن کاملAnalysis of the normal and abnormal vectorcardiogram in its own reference frame.
IN COMMON vectoreardiographic practice, vector loops are recorded in three plalne projections that are perpendicular to one another (frontal, sagittal, and horizontal planes). The arbitrary choice of these planes has been derived from body axes rather than from the spatial orientation of the vectorcardiogram or the heart itself. Several investigators1'-" have proposed, therefore, to replace the...

متن کاملThe frontal plane vectorcardiogram in old inferior myocardial infarction. Criteria for diagnosis and electrocardiographic correlation.
The early part of the frontal plane QRS loop (Frank lead system) was analyzed in 100 consecutive patients with an old inferior myocardial infarction. In order to be included in this study, all cases had to fulfill, at some time, Myers' classical ECG criteria for the diagnosis. The vectorcardiogram was made months to years after the patient's original acute episode. Several scalar and planar par...

Vectorcardiogram (VCG) recorded by both the Frank and Kimura systems were examined in 45 patients with complete right bundle branch block (RBBB) and left axis deviation (LAD) to investigate the relationship seen on electrocardiogram (ECG) between RBBB with LAD and bilateral bundle. The sample included: 13 cases of type SI, SII, SIII, SaVF; 21 cases of type SI, SII, SIII, aVF; and 11 cases of ty...
