Vectorcardiogram synthesized from a 12-lead ECG: superiority of the inverse Dower matrix
L Edenbrandt, O Pahlm - Journal of electrocardiology, 1988 - Elsevier
Vectorcardiographic (VCG) criteria for the diagnosis of, for example, myocardial infarction
and right ventricular hypertrophy, are superior to the corresponding 12-lead ECG criteria.
Contour and rotation of the QRS loops are important parts of these VCG criteria that have no
direct counterpart in the 12-lead ECG. Therefore, attempts have been made to synthesize
VCGs from 12-lead ECGs for diagnostic purposes. Visual comparison of QRS loops from the
Frank VCG and three different synthesized VCGs was made by three independent observers …
