目的观察分析β受体阻滞剂比索洛尔和美托洛尔治疗慢性心力衰竭患者频发室性早搏的疗效。方法患者均为本院门诊就诊的老年慢性心力衰竭患者,动态心电图示频发室性早搏,随机分为2组,分别给予口服比索洛尔和美托洛尔缓释片,治疗4周后,比较治疗前后和两组间频发室性早搏数量。结果β受体阻滞剂治疗频发室性早搏有效(P<0.05),比索洛尔组有效率比美托洛尔组高(P<0.05)。结论β受体阻滞剂治疗频发室性早搏疗效肯定,其中比索洛尔较美托洛尔治疗心律失常效果更明显。
Objective To observe and analyze the effect of β-blockers bisoprolol and metoprolol in the treatment of frequent ventricular premature beats in patients with chronic heart failure. Methods The patients were all outpatients with chronic heart failure in our hospital. Dynamic ECG showed frequent premature ventricular contractions and were randomly divided into two groups. The patients were given oral bisoprolol and metoprolol, respectively. After 4 weeks of treatment, Before and after treatment and the number of frequent ventricular premature beats between the two groups. Results β-blocker was effective in treating premature ventricular contractions (P <0.05), and the effective rate in bisoprolol group was higher than that in metoprolol group (P <0.05). Conclusion β-blockers are effective in treating premature ventricular contractions. Bisoprolol is more effective than metoprolol in treating arrhythmia.
