作者为探索心内直视手术后右束支传导阻滞发生的原因,对12只杂种犬进行了各种右心室游离壁切口及右束支主干、右束支外周分支损伤前后心电图变化的比较。结果显示:右室切口本身并不产生右束支传导阻滞,只有当切口过低、或偏前、或当调节束及前乳头肌向前移位,右室纵切口恰在前乳头肌基部切断右束支主干或外侧组分支时,才产生完全性右束支传导阻滞或不完全性右束支传导阻滞。其前者与右束支主干的损伤直接有关;其后者与外侧
In order to explore the cause of right bundle branch block after open-heart surgery, we compared the change of right ventricular free wall incision, right main branch of right bundle branch and right branch of peripheral branch before and after injury in 12 hybrids . The results showed that: Right ventricular incision itself does not produce right bundle branch block, only when the incision is too low, or partial, or when the adjustment beam and anterior papillary muscle shift forward, right ventricular longitudinal incision just anterior papillary muscle base Complete right bundle branch block or incomplete right bundle branch block is produced when the branch of the right or left bundle branch is severed. The former is directly related to the right bundle branch injury; the latter and the lateral
