前言本文是美国麻省总医院Dr Desanctis教授于1981年11月11日在广东省心血管病研究所作学术报告的第二个讲题。病态窦房结综合征(病窦综合征),是在起搏器发展后才使人们感到兴趣,因为安装起搏器后对这种病疗效较好。窦房结的解剖位置是在右房上部和上腔静脉交界处,长1～2 cm,宽4～5 mm。窦房结在组织切片中可着到两种细胞:一种是起搏细胞,另一种是其他的细胞。窦房结很靠近左心包膜,在心包膜外有很丰富的交感神经和迷走神经纤维,这些神经可以影响到窦房结的功能。窦房结血流供应较好,保证了它 Preface This is the second topic of an academic report by Dr Desanctis from the Massachusetts General Hospital at the Institute of Cardiovascular Disease of Guangdong Province on November 11, Sick sinus syndrome (sick sinus syndrome), is only after the development of pacemakers to make people interested, because the installation of pacemakers better effect on the disease. Anatomical location of the sinus node is in the right atrium and the superior vena cava at the junction of 1 ~ 2 cm long, 4 ~ 5 mm wide. Sinus node There are two types of cells that can be found in a tissue section: one is a paced cell and the other is another cell. Sinus node is very close to the left cardiac capsule, in the pericardium is very rich in sympathetic and vagal fibers, these nerves can affect the function of the sinus node. Sinus node blood flow is better, to ensure it
