目的探究稳心颗粒联合美托洛尔治疗心律失常的临床疗效。方法 90例心律失常患者,根据治疗方式不同分为对照组和观察组,每组45例。对照组患者采用美托洛尔治疗,观察组患者在对照组治疗基础上联合稳心颗粒治疗,观察两组患者的心电图检测结果 ,比较两组治疗后的总有效率、不良反应发生情况。结果治疗后,观察组患者的心电图各项指标均优于对照组,差异具有统计学意义(P<0.05)。观察组治疗总有效率为95.56%,高于对照组73.33%,差异具有统计学意义(P<0.05)。观察组总不良反应发生率为8.89%,低于对照组的24.44%,差异具有统计学意义(P<0.05)。结论采用稳心颗粒联合美托洛尔治疗心律失常临床疗效显著,可改善心电图指标,且安全可靠,值得临床推广。 Objective To investigate the clinical effect of Wenxin granule combined with Metoprolol on arrhythmia. Methods Totally 90 patients with arrhythmia were divided into control group and observation group according to different treatment methods, with 45 cases in each group. Patients in the control group were treated with Metoprolol. The patients in the observation group were treated with Wenxin Granule on the basis of the control group. The electrocardiogram results of the two groups were observed. The total effective rate and adverse reactions of the two groups were compared. Results After treatment, the indicators of electrocardiogram in observation group were better than those in control group, the difference was statistically significant (P <0.05). The total effective rate of the observation group was 95.56%, which was higher than that of the control group (73.33%), the difference was statistically significant (P <0.05). The incidence of adverse reactions in the observation group was 8.89%, which was lower than that in the control group (24.44%), the difference was statistically significant (P <0.05). Conclusion The clinical effect of Wenxin Granule combined with metoprolol in the treatment of arrhythmia is significant, which can improve the electrocardiographic parameters and is safe and reliable, which is worthy of clinical promotion.
