解剖观察了100例成人心脏,以前习惯上认为房室交点是后房室沟与房间沟和室间沟的交叉点。事实上这样十字交叉的点是难以找到的。文中我们赞同使用交点区域这一名词。“U”形弯曲并不恒定地出现于每一心脏。但是一旦出现,它的位置相当恒定。因此,在冠状動脉造影时可以将它作为解剖标志。认为“U”形弯曲的形成与心中静脉的内向压迫有关。讨论了房室结動脉和后降支与“U”形弯曲和房室交点的关系。
Anatomy observed 100 cases of adult heart, used to think that the atrioventricular nodal point is the intersection of the posterior chamber ditch and the room ditch and interventricular ditch. In fact, such cross-point is difficult to find. In the text we agree with the use of the term intersection. U-shaped curves do not consistently appear in every heart. But once it appears, its position is quite constant. Therefore, coronary angiography can be used as an anatomical landmark. It is considered that the formation of “U” -shaped curvature is related to the inward compression of the venous vein. The relationship between atrioventricular nodal and atrioventricular node was discussed.
