Evaluation of Ventricular De-Repolarisation Parameters in lntracerebral Hemorrhage and Cerebral Infarction Patients

Abstract

Cardiac arrest due to ventricular malign arrythmia is one of the most important causes of mortality during acute stroke. In most clinical and experimental studies; it is reported that prolonged ventricular de-repolarisation intervals may predispose to malign ventricular arrythmia. In this study, eleven intracerebral hemorrhage (IH) and thirtytwo cerebral infarction (CI) patients were recorded with a paper speed of 50 mm per second and standardisationof 2 mV a standard 12 leads ECG on first and seventh days of stroke attack. The durations of ventricular repolarisation parameters (QT, JT, QTc and JTc) and repolarisation dispersion parameters (QTd, JTd, QTc-d and JTc-d) were calculated in the standard leads. There was no statistical signficance in ventricular de-repolarisation parameters of IH patients. However; in CI patients; there was significant increase on seventh day values of QT, JT, QTc and JTc intervals according to first day values (p<0.05). Dispersion values were statistically nonsignificant between two groups. When subgroups of stroke analysed, patients in CI had a significantly longer values of QT, JT, QTc and JTc intervals on seventh day than those of IH (p<0.05). The result of this study suggest that CI patients should be more carefully evaluated for cerebrogenic cardiac arrythmia.
