尖端扭转型室性心动过速治疗体会

Treatment of Torsades Des Pointes Ventricular Tachycardia

目的观察硫酸镁与电复律终止尖端扭转型室性心动过速(Tdp VT)患者的疗效及安全性。方法回顾分析硫酸镁与电复律终止Tdp VT患者21例次的临床资料。结果TdpVT发作时应用硫酸镁终止者5例次,成功3例,成功率60·00%;电复律16例次,成功15例次,成功率93·75%。结论硫酸镁与电复律终止TdpVT发作均安全有效,电复律成功率更高。

Objective To observe curative effects and safety of magnesium sulfate and electrical cardioversion suspension torsades des pointes ventricular tachycardia （Tdp VT）. Methods The clinical data of 21 cases who had received magnesium sulfate and electrical cardioversion to suspend Tpd VT were analyzed retrospectively. Results Magnesium sulfate were used for Tpd VT in 5 patients and the success rate was 60 % , while electrical cardioversion were used in 16 patients and the success rate was 93.75%. Conclusion Both magnesium sulfate and electrical cardioversion are effective and safe in treating torsades de pointes ventryicular tachycardia, while treament of electrical cardioversion was higher success rate than that of magnesium sulfate.
