Key result
Serial sectioning of the hearts in 50 sudden unexpected infant deaths revealed petechial haemorrhages in the sinus node and internodal tracts in 11 cases (22%), suggesting myocardial hypoxia.
Observational (n=50)
Pathological findings of petechial haemorrhages in the cardiac conducting system suggest myocardial hypoxia may play a role in sudden infant death syndrome.

Hypothesis-generating for hypoxia in SIDS conduction system; leaves open any clinical role pending larger studies.
James A.J. Ferris (1973) conducted an observational in Sudden unexpected infant death (n=50). Serial sectioning of the heart was evaluated on Presence of petechial haemorrhages in the region of the sinus node and internodal conducting tissue tracts. Serial sectioning of the hearts in 50 sudden unexpected infant deaths revealed petechial haemorrhages in the sinus node and internodal tracts in 11 cases (22%), suggesting myocardial hypoxia.
