Title: Influence of metoprolol on heart rate variability and malignant ventricular arrhythmia in acute myocardial infarction
Abstract: Objective:To discover the effect of metoprolol on heart rate variability (HRV) and malignant ventricular arrhythmia (MVA) in acute myocardial infarction.Method:Seventy seven patients were randomly divided into 2 groups:metoprolol group (n=40) and control group (n=37).The metoprolol group were given metoprolol 12.5 ~50 mg twice a day.Then the HRV and MVA events in each period (1 day,7 day,6 month and 1 year) in two groups were measured and compared.Result:The HRV and MVA events were of no significant changes in both groups in a week. After six month, the MVA events were remarkably decreased in metoprolol group (P 0.01 ). Conclusion:Metoprolol may improve the HRV and reduce the MVA events in acute myocardial infarction.
