摘要
在95例成人与30例儿童心脏上,用解剖显微镜观察、解剖和测量了窦房结。在成人,此结多数可以用色苍白,质地硬.有动脉穿入等特点,在界沟上部予以确认,儿童则不易辨识。描述了右心耳嵴顶端的变异和界沟上部的切迹,并提出了窦房结三角以确认此结。对结的外表标志及其肌肉连系结合外科和功能进行了讨论。
Macro-dissection,the sinoatrialnodes(SAN)were observed andmeasured on 95 adult and 30 childcadaver hearts.In adult,most of theSANs were easily identified for itspale colour,hard texture and a tinynutrient artery,at the upper partof sulcus terminalis,but it was diffic-ult to recognize the SANs in children.The shape of the apical part of rightcrista auricularis and the notch atthe upper part of sulcus terminaliswere observed.A nodal triangle isdiscribed for identifying the SAN,and finally,the surface landmarksof the SAN and its connections withmyocardial fibers were discussed forclinical application.
