[Findings in the atrioventricular node and the bundle of His in sudden and unexpected death in childhood. Histochemical study].
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.
