Magnetocardiographic QT dispersion may aid post-MI VT risk stratification; leaves open prospective validation before clinical adoption.
Does magnetocardiographic QT interval dispersion differentiate postmyocardial infarction patients with and without susceptibility to sustained ventricular tachycardia?
Magnetocardiographic QT interval dispersion is significantly increased in post-MI patients with sustained VT, suggesting its potential utility as a noninvasive marker for arrhythmia susceptibility.
Oikarinen et al. (1998) studied this question.
