Abstract
QT dispersion measurements have gained a lot of attention by clinical cardiologists because high QT dispersion is associated with risk of arrhythmia, infarction, cardiomyopathy and other cardiac diseases. To the authors´ knowledge there is only one systematic study which investigates the reproducibility of QT dispersion measurements at different body positions with regard to biological stability. However, to the authors´ knowledge the technical aspect of uncertainty in determination of T end has so far not been quantitatively examined
