目的:探讨中医治疗冠心病心律失常的临床效果及安全性。方法:临床纳入冠心病心律失常患者84例,根据治疗方案的不同分为观察组与对照组。对照组给予美托洛尔口服,观察组在对照组治疗的基础上加入中药口服。观察两组患者的临床疗效以及治疗后临床症状评分。结果:观察组治疗有效率为85.71%,对照组治疗有效率为66.67%(P<0.05);观察组心悸、口干、心烦、胸闷、盗汗等症状评分分别为(1.62±0.15)分、(0.95±0.28)分、(2.72±0.41)分、(3.60±0.54)分、(1.63±0.83)分,对照组分别为(2.60±0.13)分、(4.24±1.32)分、(5.02±0.59)分、(4.22±0.61)分、(3.22±1.01),差异具有统计学意义(P<0.05)。结论:中医治疗冠心病心律失常具有较好的临床效果,能够显著改善患者临床不适症状。 Objective: To investigate the clinical effect and safety of Chinese medicine in treating arrhythmia of coronary heart disease. Methods: Eighty-four patients with clinical arrhythmia were divided into observation group and control group according to the different treatment regimen. The control group was given metoprolol orally, and the observation group was treated with traditional Chinese medicine on the basis of the control group. The clinical efficacy and clinical symptom scores of two groups were observed. Results: The effective rate was 85.71% in the observation group and 66.67% in the control group (P <0.05). The scores of palpitations, dry mouth, upset, chest tightness and night sweats in the observation group were (1.62 ± 0.15) (2.72 ± 0.41) points, (3.60 ± 0.54) points and (1.63 ± 0.83) points respectively in the control group and (2.60 ± 0.13) points, (4.24 ± 1.32) points and (5.02 ± 0.59) (4.22 ± 0.61) points, (3.22 ± 1.01), the difference was statistically significant (P <0.05). Conclusion: Chinese medicine treatment of coronary heart disease arrhythmia has a good clinical effect, can significantly improve the clinical symptoms of patients.
