Relationship between low-frequency components of the electroencephalogram and heart rate variability during hyperventilation.

Using synchrosqueezed wavelet transform of patterns of electroencephalograms and electrocardiograms, the features of the frequency relationships between the brain and heart rhythms during hyperventilation load in patients with vascular pathology were revealed. The data obtained can be useful in determining the neurophysiological correlates of the severity of cerebral vascular pathology. [ABSTRACT FROM AUTHOR]
