Several publications from our group and others have shown that a main cause of middle fiber block or left septal fascicular block of the left bundle of His is proximal obstruction of the left anterior descending coronary artery, before its first septal perforator branch, since this fascicle is the only one of the three fascicles irrigated exclusively by this artery. We present a case in which the phenomenon occurred transiently, causing prominent anterior QRS forces, confirmed by coronary angiography.
我们团队和其他机构的多篇出版物表明，希氏束左束支中间纤维阻滞或左间隔分支阻滞的主要原因是左前降支冠状动脉在其第一间隔穿支分支之前出现近端阻塞，因为该分支是三个分支中唯一仅由该动脉供血的分支。我们报告一例该现象短暂发生的病例，导致显著的前向QRS波力，冠状动脉造影证实了这一点。
