In 21 sudden and unexpected deaths of infants and three young children who died unexpectedly with known pathological conditions the authors examined by histochemical methods the atrioventricular node and bundle of His. The activity of "glycogen dependent" phosphorylase and the PAS reaction was in the majority week or negative. The probable cause of this finding is hypoxia, although other influences cannot be ruled out (inflammation, hypotrophy, autolysis). The activities of other enzymes (oxido-reductases ATPase, acetylcholine sterase, non-specific 1-naphtyl acetate esterase and acid phosphatase) were similar as in the normal conduction system.
在21例婴儿突然意外死亡以及3例患有已知病理状况的幼儿意外死亡病例中，作者采用组织化学方法检查了房室结和希氏束。“糖原依赖性”磷酸化酶的活性和PAS反应在大多数情况下较弱或呈阴性。这一发现的可能原因是缺氧，尽管不能排除其他影响因素（炎症、萎缩、自溶）。其他酶（氧化还原酶、ATP酶、乙酰胆碱酯酶、非特异性1-萘基乙酸酯酶和酸性磷酸酶）的活性与正常传导系统中的相似。
