cqvip:[Objectives] To observe the clinical effect and safety of Huangku Qingxin Mixture combined with Metoprolol Tartrate Tablets for patients with ventricular premature beat.[Methods] 126 patients were divided randomly into the control group (62 cases) and the treatment group (64 cases). The control group was treated with routine western medicine, and the treatment group was treated with routine western medicine combined with Huangku Qingxin Mixture, both for one month. Then, observed the changes of Myerburg score, SAS score, symptom score and dynamic electrocardiogram in the two groups before and after treatment.[Results] The total effective rate of clinical symptoms was 82.81% in the treatment group and 64.52% in the control group. Through comparison of two groups, the difference was statistically significant ( P 0.05). After treatment, Myerburg score and SAS score in the two groups were lower than those before treatment ( P 0.05). After treatment, the results of QTd and QTcd in the two groups were lower than those before treatment ( P <0.05);the results of QTd and QTcd in the treatment group were better than those in the control group ( P <0.05).[Conclusions] The application of Huangku Qingxin Mixture combined with Metoprolol Tartrate Tablets can effectively reduce Myerburg scores and SAS scores in patients with ventricular premature beat, shorten QTd and QTcd, and improve the life quality of patients. It has no adverse clinical reaction.
