摘要
目的:观察静脉注射美托洛尔对急性冠状动脉综合征合并室性心动过速(室速)风暴临床疗效及其安全性。方法:将急性冠状动脉综合征合并室速风暴64例患者,随机分为对照组(30例)和美托洛尔组(34例)。对照组患者仅于静脉应用利多卡因或胺碘酮基础上采用电复律治疗,美托洛尔组患者在上述治疗基础上给予静脉注射美托洛尔。结果:美托洛尔组终止反复室速、心室颤动成功率显著高于对照组(91.2%∶30.0%,P<0.05),终止室速及心室颤动所需放电次数显著少于对照组[(4.19±3.27)∶(8.48±5.12)次,P<0.05)],房室传导阻滞的发生率显著高于对照组(20.6%∶6.7%,P<0.05),与对照组低血压的发生率比较,差异无统计学意义(41.2%∶33.3%,P>0.05)。结论:对于急性冠状动脉综合征合并室速风暴患者在常规治疗基础上,及时足量地静脉注射美托洛尔治疗是有效和安全的。
Objective:To evaluate the effect of Metoprolol on ventricular tachycardia storm secondary to acute coronary syndrome.Method:Sixty-four patients with ventricular tachycardia storm secondary to acute coronary syndrome from May 2006 to December 2008 were randomly divided into two groups:control group and Metoprolol intervention group.Patients in control group were treated with Lidocaine or Amiodarone and electric cardiover-sion,while patients in Metoprolol intervention group were intravenously administrated with Metoprolol injection on the basis of the treatment of control group.Result:The success rate of terminating repeated ventricular tachy-cardia or ventricular fibrillation of Metoprolol intervention group was significantly higher than that of control group (91.2%vs 30.0%,P〈0.05).The necessary discharge times of terminating ventricular tachycardia or ventricular fibrillation in Metoprolol intervention group was considerably decreased than those in control group([4.19±3.27] vs[8.48±5.12]min,P〈0.05).The incidence of atrioventricular block in Metoprolol intervention group was markedly increased compared with that in control group(20.6%vs 6.7%,P〈0.05).No significant difference was found in the incidence of hypotension(41.2%vs 33.3%,P〈0.05).Conclusion:It is important to be aware of the existence of ventricular tachycardia storm secondary to acute coronary syndrome.On the basis of conventional treatment,intravenous administration of Metoprolol injection is a safe and effective therapy to ventricular tachycardia storm.
