【摘要】 目的 评价异搏定治疗室上性心动过速的疗效和安全性。方法 14例室上性心动过速患者静脉注射异搏定,观察转复窦性心律情况。结果 静脉注射异搏定起效时间为(3.4±1.5)min,治疗有效率为85.7%。结论 异搏定不仅能有效地转复室上性心动过速,而且不良反应小。

    【Abstract】 Objective To investigate the effectiveness and safety of verapamil in treatment of supraventricular tachycardia(SVT).Methods Fourteen patients with SVT were treated with verapamil intravenously.The conversion rate and adverse effects were recorded.Results Twelve(85.7%)of the fourteen patients with SVT were successfully converted to sinus rhythm with verapamil treatment.The mean conversion time was(3.4±1.5)minutes.No adverse effects were observed.Conclusion Verapamil injection can be used to convert SVT to sinus rhythm effectively with little side effects.
