Does postprocessing of QT measurements by ECG pattern matching reduce intrasubject QTc variability compared to manual measurements?
Morphological pattern adjustment of QT interval measurements significantly reduces intrasubject QTc variability, which can improve data quality and reduce the required sample size for thorough QT studies.
