ABSTRACT
Objective It is to observe the clinical effect of Wenxinkeli combined with metoprolol on frequent ventricular premature beat (FVEB).Methods234 patients with FVEB were randomly divided into the study group and control group.117 patients in the control group were treated with metoprolol combined with placebo, and 117 patients in the stduy group were treated with Wenxinkeli combined with metoprolol.4 weeks were a course of treatment.After four weeks, the heart rate variability, QT interval dispersion and 24h average heart rate of two groups were observed, and the clinical effect were evaluated.ResultsAfter 4 weeks of treatment, 5 cases in the study group and 7 cases in the control group were excluded.The efficiency of control group and study group were 89.29% and 79.09% (P<0.05), respectively.After treatment, the SDNN、SDANN、RMSSD and PNN50 of two groups were significantly higher than those before treatment(P<0.05), and the increase value of the study group was higher than that of the control group(P<0.05).After treatment, the QTd and QTcd of two groups were decreased than those before treatment(P<0.05), and the decreased value of the study group was higher than that of the control group(P<0.05).There was no significant change in the heart rate of the two groups before and after treatment.ConclusionWenxinkeli combined with metoprolol in the treatment of FVEB can prolong HRV, reduce QTd, improve the treatment effect, has no significant effect on the heart rate.
