Intravenous Esmolol in Treatment of 26 Patients with Ventricular Electrical Storm

Objective To observe the clinical efficacy and safety of intravenous Esmolol in treatment of ventricular electrical storm. Methods A total of 26 patients admitted for ventricular electrical storm during June 2010 and February 2013 were intravenously injected with loading dose of 0. 5 mg /kg Esmolol injection,and then were given 0. 05 mg /( kg ·min) of maintenance dose within 36-72 hours. The clinical efficacy was observed,and safety was evaluated. Results The symptoms of ventricular tachycardia and ventricular fibrillation in the 24 patients were effectively controlled,and the controlling success rate was 92. 3%. Three patients with severe sinus bradycardia and three patients with decreased blood pressure recovered after corresponding treatment. Two patients died of repeated ventricular fibrillation within 72 hours of treatment. Conclusion Intravenous Esmolol in treatment of ventricular electrical storm is effective and safe.
