自Keith和Flack(1906)发现窦房结以来,一些国外学者先后对窦房结的形态、结构及神经支配进行了研究。但国内这方面的报导很少,迄今仅张朝佑、侯广琪等对成人窦房结的亚微构造及狗的窦房结神经支配进行过观察。关于窦房结内是否存在神经节的问题,国内外仍有不同的意见。为此,本文对7例新生儿心脏窦房结的位置、构造及神经供应进行了光学显微镜观察,并讨论了神经节和窦房结的关系。材料与方法所有的7例新生儿心脏均经肉眼检查无先天异常,其中男性3例,女性4例。另取3
Since the discovery of the sinus node by Keith and Flack (1906), some foreign scholars have studied the morphology, structure and innervation of the sinus node. However, there are few reports in this area in our country. So far, only Zhang Zuoyou and Hou Guangqi have observed the submicrostructure of adult sinus node and the sinoatrial node innervation of dogs. Regarding the presence of ganglia in the sinus node, there are still different opinions at home and abroad. To this end, this paper on 7 cases of neonatal cardiac sinus node location, structure and nerve supply was observed by light microscopy, and discusses the relationship between the ganglion and the sinus node. MATERIALS AND METHODS All seven neonatal hearts were examined by visual inspection for absence of congenital anomalies, including 3 males and 4 females. Another 3
