    Heart Rate Variability (HRV) is an indicator of health status in the general population and of adaptatio n to stress in athletes. In this paper we compare the performance of two systems to measure HRV: (1) A commerc ...
  • New indices for quantification of the power spectrum of heart rate variability time series without the need of any frequency band definition 

    Ramos Castro, Juan José; Padullés, M.; Marina, M.; Bescós, R.; Iglesias, X.; Rodriguez, F. A.; García González, Miguel Ángel; Fernández Chimeno, Mireya; Ferrer, J.; Escorihuela, R.M.; Parrado Romero, Eva; Capdevila, L.; Benitez, A.; Angulo, R. (IOP PUBLISHING LTD, 2011-06-07)
