早期可逆性束支阻滞,可能是永久性束支阻滞的先兆,应给予关注。由于人类心脏传导系统功能的特殊性,目前尚不能进行活检,这就给探索人类早期束支阻滞机制带来困难,因而进行动物实验研究。本实验目的是通过阻断家兔心脏左前分支的血液供应,
Early reversible bundle branch block may be a precursor to permanent bundle branch block, should be given attention. Due to the particularity of the function of human cardiac conduction system, biopsy can not be performed at present, which makes it difficult to explore the mechanism of early bundle branch blockage in humans. Therefore, animal experiments are conducted. The purpose of this experiment is to block the blood supply to the left anterior branch of the rabbit heart,
