DIAZ GARCIA, Carlos Manlio et al. Effect of age on heart rate variability in healthy people. Rev Cubana Invest Bioméd [online]. 2008, vol.27, n.1. ISSN 0864-0300.

Introduction: the heart rate variability is an instrument of quantification of the autonomous activity before different pathophysiological situations. Objectives: To characterize the effect of age on the autonomous control of the heart and elucidate the possible kindnesses of little exploited indexes in this field. Methods: the study was conducted in a population of sound subjects aged 17-44. Results: It was obtained a decrease of variability in both sexes with age, using indexes derived from Poincaré's Graphic. Conclusions: The reduction of the heart rate variability is due to the generation of the neurovegetative system and the methods of analysis used proved to be less variable than those commonly used by other authors.

Keywords : Autonomous regulation; heart rate variability; age.
