Abstract
The association of left anterior fascicular block (LAFB) with left septal fascicular block (LSFB) characterizes a left bifascicular block subtype rarely described in the literature, probably due to the fact that most researchers are not aware of the existence of the left septal fascicle. We describe a case with this transient intraventricular dromotropic disturbance due to left anterior descending coronary artery subocclusion.
摘要
左前分支阻滞（LAFB）与左间隔分支阻滞（LSFB）相关，这是一种文献中很少描述的左双分支阻滞亚型，可能是因为大多数研究人员并未意识到左间隔分支的存在。我们描述了一例因左前降支冠状动脉次全闭塞导致这种短暂性室内传导紊乱的病例。
