摘要
目的:探讨美托洛尔静注治疗急性心肌梗死后多形性室速的疗效。方法:2012年6月-2013年6月收治急性心梗合并多形性室速患者5例,给予美托洛尔5 mg静注,0.5~1 mg/min,2 min后重复给药,用药次数3~4次,总量15~20 mg,改用美托洛尔12.5~25 mg口服,2次/d。结果:4~6 h后,患者心电监护无多形性室速发生。结论:静注美托洛尔在急性心梗溶栓后出现的频发多形性室速的治疗是行之有效的。
Objective:To investigate the effect of metoprolol injection in the treatment of polymorphic ventricular tachycardia after acute myocardial infarction.Methods:After using urokinase in patients with acute myocardial infarction polymorphic ventricular tachycardia happened frequently,given metoprolol 5 mg intravenous injection,0.5~1 mg/min,repeated administration after 2minutes,given 3~4 times,a total of 15~20 mg,12.5~25 mg with metoprolol orally 2 times/day.Results:After 4~6 hours,the ECG monitoring with non polymorphic ventricular tachycardia happened.Conclusion:Intravenous injection of metoprolol in the treatment of frequently polymorphic ventricular tachycardia occurred after thrombolysis in acute myocardial infarction is effective.
