目的:观察静脉注射硫酸镁对快速型房颤的治疗效果。方法:选择46例急诊就诊的快速型房颤患者,随机分为治疗组和对照组,除常规治疗外,分别给予静脉输注硫酸镁(给药方法:2.5 g硫酸镁20 min内输完,继之以第二个2.5 g硫酸镁在2 h内输完)和安慰剂,观察两组患者治疗后心律和心室率的变化。结果:在给药后的2.5 h内,治疗组患者心室率降至100次/min以下者显著多于对照组(P<0.05),转复为窦性心律者也显著多于对照组(P<0.05)。结论:静脉注射硫酸镁能增强快速型房颤的治疗效果。
Objective: To observe the therapeutic effect of intravenous magnesium sulfate on atrial fibrillation. Methods: Forty-six patients with acute AF were enrolled in this study. Patients were randomly divided into treatment group and control group. In addition to conventional treatment, intravenous infusion of magnesium sulfate (2.5 g magnesium sulfate was given within 20 min, Followed by a second 2.5 g of magnesium sulfate in 2 h lost) and placebo to observe the changes in heart rate and ventricular rate after treatment in both groups. Results: Within 2.5 h after treatment, the ventricular rate decreased to 100 beats / min in the treatment group than in the control group (P <0.05), and those in the sinus rhythm were significantly more than those in the control group (P <0.05). Conclusion: Intravenous injection of magnesium sulfate can enhance the therapeutic effect of atrial fibrillation.
