心律平是一种新的、抗心律失常药,它除了具有膜稳定作用外。还是一种弱的β受体阻滞剂和轻度的钙离子拮抗剂。作者报道用心律平治疗12例伴左心机能不全(射血分数均低于0.40)的室颤或症状性室速患者。12例患者过去均经1～4种抗心律失常药治疗无效。12例中10例为冠心病,2例为非特异性扩张型心肌病。用药前4例有室颤史,4例有持续性室速史,4例有非持续性室速史,作者用心律平口服,首次负荷量为
Cardiac rhythm is a new, anti-arrhythmic drug that, in addition to its membrane stabilizing effect, It is also a weak beta blocker and mild calcium antagonist. The authors report that 12 patients with ventricular fibrillation or symptomatic VT were treated with heart rhythm for 12 patients with left ventricular dysfunction (ejection fraction less than 0.40). All 12 patients were previously treated with 1 to 4 antiarrhythmic drugs. Of the 12 patients, 10 were coronary heart disease and 2 were nonspecific dilated cardiomyopathy. 4 cases before treatment with ventricular fibrillation history, 4 cases of persistent ventricular tachycardia, 4 cases of non-sustained VT history, the author oral administration of rhythm, the first load was
