Heart rate variability analysis during an Endurance Mountain Trail Race
(Universitat Politècnica de Catalunya, 2019-07-09)
Bachelor thesis
Restricted access - author's decisionThe autonomic nervous system (ANS) is the control mechanism of heart rate variability (HRV). Assessing HRV can lead to prominent information about this control system, taking into account the two control sympathetic and ... -
Modeling of heart rate variability and respiratory muscle activity in organophosphate poisoned patients
(2019-11-01)
Article
Open AccessWe propose an extended model of cardiovascular regulation to assess heart rate variability in patients poisoned with organophosphate during their treatment with mechanical ventilation. The model was modified to fit a ... -
