Clinical TrialQT dispersion. Is it an independent risk factor for in-hospital mortality in patients with intracerebral hemorrhage?
Electrocardiographic repolarization changes, comprising QT prolongation, are most commonly seen after intracerebral hemorrhage. In this study in patients with intracerebral hemorrhage (ICH), QT dispersion and its daily changes were examined and the relation between QT dispersion and in-hospital mortality assessed. In 28 patients with intracerebral hemorrhage, diagnosed by computerized tomographic scanning, an ECG was obtained on the day of admission to hospital and then serial ECGs were recorded on the following four consecutive days. ⋯ During the five days, QT, QT peak, and QT-QTpeak dispersion values were significantly higher in patients with intracerebral hemorrhage than in the control subjects (p < 0.001). There were no statistically significant differences in two patient groups with intracerebral hemorrhage who died and who were discharged in terms of mean QT, QTpeak, and QT-QTpeak dispersion values. In conclusion, QT, QT peak, and QT-QTpeak dispersion values were significantly greater in patients with intracerebral hemorrhage than in the control subjects, but QT, QT peak, and QT-QT peak dispersions were not independent risk factors for in-hospital mortality in patients with intracerebral hemorrhage.
