完全性左束支传导阻滞多为病理性,通过药物治疗恢复者甚为少见。最近我们应用低分子右旋糖酐加654-2静脉滴注治疗3例,其中1例心电图恢复正常,2例好转,现报告于下。临床资料与方法:3例均为男性,年龄最小52岁,最大73岁。其中冠心病2例,扩张型心肌病1例,心电图均示典型完全性左束支体导阻滞,持续存在一年以上。均采用低分子右旋糖酐250ml加654-2 10mg静 Complete left bundle branch block mostly pathological, recovered by drug treatment is rare. Recently we applied low molecular weight dextran plus 654-2 intravenous infusion of three cases, of which 1 electrocardiogram returned to normal, 2 cases improved, the report is below. Clinical data and methods: 3 cases were male, the youngest 52 years old, maximum 73 years old. Of which 2 cases of coronary heart disease, dilated cardiomyopathy in 1 case, ECG showed typical complete left bundle branch block, persist for more than a year.
