Abstract

Positivity of cTnT on admission is associated with a significantly higher temporal inhomogeneity of ventricular repolarization and a higher incidence of malignant RAs, which suggests more advanced microvascular injury. Early successful primary PCI ultimately results in a significant recovery of parameters of QT interval and mean RR interval in all patients, although it was significantly delayed in patients in the cTnT+ group.
