Abstract:ObjectiveTo observe the clinical effect of metoprolol combined with Wenxin granules for arrhythmia by ambulatory electrocardiography(AECG) Methods82 patients with arrhythmia were randomly divided into two groups,each with 41 cases Only metoprolol were taken in the control group,while combined therapy of Wenxin granules and metoprolol were underwent in the treatment group The clinical effect in both groups were compared,24 hour dynamic electrocardiogram and adverse reaction before and after treatment in the two groups were observed and compared ResultsAfter treatment,the total effective rate was 9512% in the treatment group and 5854% in the control group,the difference was statistically significant(P<005) The premature beat in two groups were improved compared with those before treatment(P<005),and the improvements in the treatment group were superior to those in the control group(P<005) During treatment,the incidence rate of adverse reaction was 1951% in the treatment group and 1463% in the control group,the difference was no statistically significant(P>005) ConclusionThe therapy of metoprolol combined with Wenxin granules for patients with arrhythmia can effectively improve the clinical symptoms,has low incidence rate of adverse effect,and is worthy to be promoted in clinical practiceKey Words:Arrhythmia;Metoprolol;Wenxin granules;24 hour dynamic electrocardiogram
