[Standardization of oculo-cardiac reflex in infants under 3 months of age].

: The authors present a standardization of the oculocardiac reflex carried out in early-age infants (under 3 months). This standardization is easy to perform. It takes into account the fall of the cardiac frequency, the asystoly and the range of bradycardia until its normalisation. Thus, it allows inter or intra individual comparison and can be applied to the study of infants at risk for sudden infant death syndrome.
