| 摘 要： | 心脏传导系统（CCS）包括窦房结（SAN）、房室结（AVN）、房室束（又称希氏束，HB）、左右束支（LBB，RBB）及其终末纤维网，其功能是把心脏搏动的冲动传导到整个心脏，以协调心脏的节律性收缩．近年来，CCS病变与猝死的关系引起重视，已有研究表明，一些猝死与CCS的病变有关。但在实际应用中，必须将CCS增龄变化同其病变区分开来，以免误将其正常增龄变化视为病变，导致错误的结论．1SAN的年龄变化在光镜水平，Lev[1]首先对53例4个月胎儿至90岁老人的SAN进行了分年龄组观察；Davies[2]对50岁以下和75岁以上两组各50例的SAN…

| Abstract: | This paper reviews the ageing changes of the human cardiac conduction system according to the ever published literature. In ageing process, the cardiac conduction system shows typical physiological changes: (1) differentiation, development and maturation in fetal and postnatal period, (2)reduction of the specific conduction cells and the changes of the whole node volumes. (3) fibrosis and fat infiltration. It is stressed that while explaning the causes of sudden death with the knowledge of cardiac conduction system diseases, the forensic pathologist ahould be able to distinguish the pathological changes from that of the normalagemg. |
