      Article
      Open Access
      Introduction: The study of arousal is crucial as it helps to understand the role of increased physiological and psychological activation in emotions, motivation, cognitive performance, stress responses, sleep-wake cycles, ...

    • On the application of short-term heart rate variability indices to track changes in cognitive arousal 

      Mohammadpoor Faskhodi, Mahtab; García González, Miguel Ángel (SciTePress, 2023)
      Conference lecture
      Open Access
      Studies have demonstrated that Heart Rate Variability (HRV) can be utilized as an effective tool for monitoring the level of arousal. The autonomic nervous system (ANS) is frequently measured by heart rate and principally ...
    • On the use of fractional calculus to improve the pulse arrival time (PAT) detection when using photoplethysmography (PPG) and electrocardiography (ECG) signals 

      Mohammadpoor Faskhodi, Mahtab; García González, Miguel Ángel; Fernández Chimeno, Mireya; Guede Fernández, Federico; Mateu Mateus, Marc; Capdevilla, Lluis; Ramos Castro, Juan José (Public Library of Science (PLOS), 2024-02-16)
      Article
      Open Access
      The pulse arrival time (PAT) has been considered a surrogate measure for pulse wave velocity (PWV), although some studies have noted that this parameter is not accurate enough. Moreover, the inter-beat interval (IBI) time ...
    • Using ultra-short-term Heart Rate Variability (HRV) analysis to track posture changes 

      Mohammadpoor Faskhodi, Mahtab; Fernández Chimeno, Mireya; García González, Miguel Ángel (Institute of Electrical and Electronics Engineers (IEEE), 2024-07-05)
      Article
      Open Access
      Body posture significantly influences heart rate variability (HRV) through the autonomic nervous system (ANS), which maintains hemodynamic stability by balancing sympathetic and parasympathetic activity. Postural changes ...
