May refine post-MI repolarization assessment; leaves open prospective validation for risk stratification.
Does spatial distribution of QT dispersion using multichannel magnetocardiograms improve discrimination between healthy subjects and post-MI patients compared to standard QT dispersion?
Spatial distribution patterns of QT dispersion using magnetocardiograms may provide a more differentiated marker for repolarization pathology and risk than standard QT dispersion.
Leeuwen et al. (1996) studied this question.
