In most cases, a left bundle-branch block pattern on an electrocardiogram is a postoperative phenomenon. Under rare circumstances, it can be found in patients after myocardial infarction or in patients with hypertrophic cardiomyopathy, or it can be exercised induced. We describe a pediatric patient with propionic aciduria, dilated cardiomyopathy, and rate-dependent left bundle-branch block on her electrocardiogram.
在大多数情况下，心电图上的左束支传导阻滞模式是一种术后现象。在极少数情况下，可在心肌梗死后的患者或肥厚型心肌病患者中发现，也可能是运动诱发的。我们描述了一名患有丙酸尿症、扩张型心肌病且心电图显示有心率依赖性左束支传导阻滞的儿科患者。
