Time-frequency analysis of the heart rate variability during arousal from sleep, with and without EMG activation, coming from five obese healthy subjects was performed. Additionally, a comparative analysis of three time-frequency distributions, smooth pseudo Wigner–Ville (SPWVD), Choi–Williams (CWD) and Born–Jordan distribution (BJD) is presented in this(More)
The goal of this work was to apply a time-varying spectral approach to study the dynamic changes in Heart Rate Variability (HRV) produced by the arousal from sleep in obese patients with and without Obstructive Sleep Apnea (OSA). We studies 10 subjects, group I without OSA and group II with OSA diagnostic. RR intervals series was obtained from ECG records.(More)
