Abstract
Background: Cardiac dynamics have been evaluated from physical-mathematical theories like probability and dynamical systems, allowingto developing diagnosis and clinical application predictions. Objective:To measure the probability of normal neonatal heart rates distribution,for doing a mathematical characterization, objective and reproducible.Methods: It have been analyzed 10 normal dynamics through continuousrecords and holters, taking maximum and minimum values of heart ratesper hour during 21 hours. Ranges of 5 beats/min were generated; obtaineddistributions in probability space for heart rates were analyzed, to searchnormality mathematical characteristics for neonatal cardiac dynamics.Results: The probabilities of the evaluated ranges varied between 0.02272and 0.2826; also, in three of the ranges, all the dynamics showed aminimum probability or zero. Conclusions: A general characterization, objective and reproductible, of normal neonatal cardiacdynamics, was developed.
