观察静脉应用各种剂量地尔硫(艹卓)控制房颤、房扑的心室率之效果及其副反应。 方法 62例房颤患者和22例房扑患者在静脉用药前心室率>120次/分,首先在2分钟内静推20mg地尔硫(艹卓)。如在15分钟内没有获得预期疗效(转为窦律,心室率<100次/分,或心室率比发作时降低20％以上)或临床上需进一步降低心率,可以静推25mg如仍无效,该病例退出,另选治疗方案,对上述方法 Observation of intravenous doses of diltiazem (艹 Zhuo) control of atrial fibrillation, ventricular rate of atrial flutter effect and its side effects. Methods 62 patients with atrial fibrillation and 22 patients with atrial flutter before intravenous ventricular rate> 120 beats / min, first intravenous infusion of 20mg diltiazem within 2 minutes. If you do not get the desired effect within 15 minutes (to sinus rhythm, ventricular rate <100 beats / min, or more than 20% lower ventricular rate than attack) or clinical need to further reduce the heart rate, you can push 25mg if still inactive, The case exits, an alternative treatment regimen to the above method
