Clinical observation on the treatment of premature ventricular beats with Zaobo decoction combined with bisoprolol / 国际中医中药杂志

ABSTRACT

Objective To observe the clinical effects of Zaobo decoction combined bisoprolol treating premature ventricular contractions.Methods 108 patients of ventricular premature beat were recruited intoa control group and an observation group (n=54) according to the random number table method.The control group was treated with bisoprolol, while the observation group was treated with Zaobo decoction on the basis of the control group, and both groups were treated for 8 weeks.24 h dynamic electrocardiogram (ECG), renin activity plasma (PRA), angiotensin Ⅱ (angiotensionⅡ) and ALD (Ang) were observed before and after treatment.The clinical effects were evaluated.Results The total effective rate showed significant difference between the observation group and the control group (75.9％ vs.57.4％;x2=4.167, P=0.041) after the treatment.After treatment, Ang-Ⅱ (56.22 ± 12.7 pg/ml vs.68.45 ± 12.7 pg/ml, t=5.004) in the observation group was significantly lower than the control group (P＜0.01);24 h sinus RR interval standard deviation (129.16 ± 28.56 ms vs.116.13 ± 17.38 ms, t=2.864), every 5 min sinus RR interval mean standard deviation within 24 h (123.57 ± 25.24 ms vs.112.46 ± 18.23 ms, t=2.622), and within 24 h of sinus RR interval difference rms (31.76 ± 11.42 ms vs.22.64 ± 10.32 ms, t=4.354) in the observation group were significantly higher than the control group (P＜0.01).Conclusion Zaobo decoction combined with bisoprolol can effectively improve heart rate variability, regulate rernin vascular angiotensin system, and improve the clinical efficacy of the patients with ventricular premature beat.
