Questions reliance on electrical positions for anatomic inference on ECG; leaves open validation of direct 3D electromotive force descriptions.
Does the electric axis on conventional electrocardiograms correlate with the anatomic orientation of the heart determined by biplane angiocardiography in patients?
The concept of 'electrical positions' of the heart does not correlate with true anatomic orientation and should be replaced by direct 3D description of the mean electromotive force.
Guntheroth et al. (1961) studied this question.
