窦房结和房室结是心传导系的重要部分,对滋养这两个结的窦房结动脉和房室结动脉的解剖知识,不论基础医学工作者或临床医生都比较重视。早在1907年,Keith和Flack发现窦房结时,即开始描述了窦房结动脉。这支血管除营养窦房结外,还分布至上腔静脉口附近,故Gross又称其为上腔静脉口支(r.ostii cavaesuperioris)。由于它首经Keith和Flack描述,也称为Keith-Flack动脉。James认为窦房结动脉名称比较适宜,简短清楚、含意明确,故目前常应用此名。房室结动脉又称纤维中隔支
Sinus node and atrioventricular node conduction is an important part of the heart, nourish the two nodes of the sinus node arteries and atrioventricular node anatomy knowledge, regardless of basic medical workers or clinicians are more attention. As early as 1907, when the sinoatrial node was discovered by Keith and Flack, the sino-atrial node arteries were described. In addition to the nutrition of the sinus node of the blood supply, but also distributed to the vicinity of the superior vena cava mouth, so Gross also known as the superior vena cavaesuperioris (r.ostii cavaesuperioris). Because it is first described by Keith and Flack, it is also known as the Keith-Flack artery. James believes that sinoatrial node artery name more appropriate, brief and clear, the meaning is clear, so the current use of this name. Atrioventricular node artery, also known as fibrous septum
