摘要

Nonlinear analyses of infant heart rhythms reveal a marked rise in the complexity of the electrocardio- gram with maturation. We find that normal mature infants (gestation ≧ 35 weeks) have complex and distinctly nonlinear heart rhythms (consistent with recent reports for healthy adults) but that such nonlinearity is lacking in preterm infants (gestation ≦ 27 weeks) where parasympathetic- sympathetic interaction and function are presumed to be less well developed.
