Abstract：Objective To investigate the changes of QT dispersion(QTd) and its clinical significance for patients with acute cerebral infarction after successful thrombolytic therapy and nonthrombolytic ones.MethodsSeventyseven patients with acute cerebral infarction were divided into thrombolytic recanalization group (group A, 41 cases) and nonthrombolysis group (group B, 36 cases). Between the 2 groups, the changes of QTd and QTcd(corrected QT dispersion) and the occurrence of ventricular arrhythmia were analysed.ResultsCompared with group B, QTd, QTcd and the occurrence of ventricular arrhythmia in group A all decreased significantly with statistically significant differences(P<0.05).ConclusionAmongst patients with acute cerebral infarction, their QTd and QTcd both decrease and the occurrence of ventricular arrhythmia also reduces significantly after successful thrombolytic therapy.
