Vectorcardiography provides additional diagnostic value over standard 12-lead ECG for complex conduction abnormalities and ventricular hypertrophy.

May support vectorcardiography for complex ECG interpretation; leaves open prospective validation in contemporary practice.
The spatial vectorcardiogram is of clinical value in interpreting complex 12-lead scalar electrocardiograms in diagnosis of ventricular hypertrophy and abnormal conduction disturbances. The VCG is also helpful in detecting the preexcitation syndrome, not apparent in the scalar ECG. The orthogonal XYZ lead system has simplified computerization of the graphic data.
