The invention belongs to the cross technical field of
biomedical engineering and nerve regulation technology. According to the brain-heart linkage transcranial strong
alternating current stimulation
feedback control method and
system,
heart rate variability characteristics are obtained according to electroencephalogram signals, electroencephalogram
signal characteristics are obtained according to the electroencephalogram signals, and a
dynamic coupling index is determined according to the electroencephalogram signals and electrocardiosignals; when the
heart rate variability characteristic is greater than or equal to a corresponding
heart rate characteristic baseline threshold value, the electroencephalogram
signal characteristic is greater than or equal to a corresponding electroencephalogram characteristic baseline threshold value, and the
dynamic coupling index is greater than or equal to a set threshold value, judging that the
emotional disorder is improved, and keeping the intensity of the stimulation current unchanged; otherwise, increasing the intensity of the stimulation current to a set threshold value until the
emotional disorder is improved. Through combined calculation of the electroencephalogram signals and the electrocardiosignals,
dynamic monitoring and accurate evaluation of the process of treating the
emotional disorder through transcranial strong
alternating current stimulation are achieved, and the accuracy of electrical stimulation is guaranteed.
