Cube-tetrahedral discrepancies advise caution in historical data comparisons; leaves open standardization with modern orthogonal leads.
How do vectorcardiograms recorded with the cube and tetrahedral lead systems compare in normal and pathological cases?
The discrepancy between cube and tetrahedral lead systems highlights the need for standardization and adoption of modern electrically orthogonal lead systems in vectorcardiography.
Thulesius et al. (1962) studied this question.
