Two frequency bands, where different physiological information is expected, are analyzed: low frequency (LF) influenced by both sympathetic and parasympathetic activity, and high frequency (HF) influenced by parasympathetic activity. As PATF, PTTD is influenced by PTT, but in contrast to PATF, PTTD is not influenced by the pre-ejection period (PEP). This is advantaging in certain applications such as arterial stiffness assessment or blood pressure estimation. Results showed higher correlation between PTTD and PATF during rest stages than during tilt stage, when the PEP dynamics have stronger effect in PATF dynamics. This suggests that PTTD variability can potentially be a surrogate of PTT variability that is not influenced by PEP, which is advantaging in the previously mentioned applications. However, further studies must be elaborated in order to evaluate the potential of PTTD in such specific applications. info:eu-repo/grantAgreement/ES/DGA/T96 info:eu-repo/grantAgreement/ES/FIS/PI12-00514 info:eu-repo/grantAgreement/ES/MINECO/TEC2013-42140-R info:eu-repo/grantAgreement/ES/MINECO/TIN2013-42140-R info:eu-repo/grantAgreement/ES/MINECO/TIN2014-5356-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0003-1272-0550 Bailón, Raquel Universidad de Zaragoza (orcid)0000-0003-3434-9254 Laguna, Pablo Universidad de Zaragoza Marozas, Vaidotas Rapalis, Andrius (orcid)0000-0001-7285-0715 Gil, Eduardo Universidad de Zaragoza 5007 520 Universidad de Zaragoza Dpto.
