Increased QT dispersion in late pregnancy may reflect physiological adaptation; leaves open its value as an arrhythmia marker and warrants prospective outcome studies.
Does late pregnancy alter QT dispersion and T-loop morphology compared to healthy non-pregnant women?
Late pregnancy physiologically increases QT dispersion and alters T-loop morphology, suggesting that QT dispersion is influenced by the spatial position of the heart and reflects the complete process of ventricular repolarization rather than solely indicating arrhythmia risk.
