Power spectral analysis of heart rate variability and baroreflex gain.
Experimental open-loop studies [1] indicate that when a sinusoidal pressure function is forced onto the arterial baroreceptors, a sinusoidal oscillation is reflexly transferred on to R-R interval and arterial pressure, with a rapid fall of gain with increasing oscillatory frequencies. Sleight et al. [2] addressed this issue in man with an elegant approach employing frequency domain analysis. In...
متن کاملDetection of epileptic seizures with a modified heart rate variability algorithm based on Lorenz plot
PURPOSE In order to assess whether focal epileptic seizures can be detected and distinguished from exercise we evaluated four different heart rate variability (HRV) methods with short term moving window analysis of 30, 50 or 100 R-R intervals or seconds per analyzed window. METHODS The four methods consisted of: (1) reciprocal high frequency power based on Fast Fourier Transformation, (2) Car...
متن کاملPower spectral analysis of heart rate variability after spinal anaesthesia.
Power spectral analysis of heart rate (HR) variability is a useful tool with which to assess cardiac autonomic activity. The low frequency bands have been considered as both sympathetically and parasympathetically mediated components, while the high frequency bands have been assumed to be the parasympathetically mediated respiratory components. It has been anticipated that spinal anaesthesia to...
متن کاملHeart rate variability--a shape analysis of Lorenz plots.
A new quantitative geometrical method to analyse heart rate variability is presented. The standard image analysis techniques were applied to the grey scale images of Lorenz plots, and the outlines of the attractor areas were determined via a contour following procedure based on a maze walking algorithm. For graphs of simple compact shape, the attractor region contours were described in terms of...
متن کاملSpectral analysis of Heart Rate Variability
The tools that you learn in the stationary stochastic processes course are fundamental and can be applied for extraction of information in many areas. In the following description, the contents of your data-files will be explained. For the two scheduled computer sessions, a number of investigations and questions are proposed. These are chosen to give you ideas for your further analysis. Some us...
