The atrioventricular conduction system of 27 infants coming to autopsy was examined by histochemical methods. Twenty one were sudden infant deaths; six were explained deaths. A decrease of oxidoreductases and hydrolases activities was found in clusters of conducting cells protruding from the atrioventricular (AV) node and His bundle left into the collagen of the septum. These findings reflect regressive changes connected with reduction of the AV conducting system during postnatal development.
采用组织化学方法检查了27例尸检婴儿的房室传导系统。其中21例为婴儿猝死;6例为死因明确的死亡。在从房室(AV)结和希氏束突出并伸入间隔胶原中的传导细胞簇中,发现氧化还原酶和水解酶活性降低。这些发现反映了与出生后发育过程中房室传导系统减少相关的退行性变化。
