Abstract:
Objective The aim of this study was to evaluate the value of QT dispersion and heart rate variability in predicting early ventricular fibrillation during hospitalization after acute myocardial infarction.Methods Seventy-two patients underwent 24-hour Holter monitoring within 6 hours after onset of acute myocardial infarction.They were divided into 2 groups,VF group (12 cases) and Non-VF group (60 cases),based on whether they had experienced an episode of ventricular fibrillation during their hospitalization.Index of QT dispersion and heart rate variability were calculated on the basis of 24 hours Holter recording.Results The HRV indexes showed significant difference (respectively,.P.
