title: [The psychophysiological features of nonepileptic paroxysmal disorders].
abstract: 22 patients with panic disorder without agoraphobia, 19 patients with paroxysmal atrial fibrillation and 43 healthy control subjects with use clinic technique, psychometric, neuropsychological, neurophysiological methods (quantitative EEG and auditory event-related potentials P300) were examined. Patients with panic disorder was differed from patients with paroxysmal atrial fibrillation by higher level of anxiety and greater degree cognitive functions disturbances. In comparison with healthy control subjects at panic disorders increased of P300 peak amplitude and the spectral power of EEG beta and theta bands in the right hemisphere was observed, at paroxysmal atrial fibrillation--decreased of P300 peak amplitude and the spectral power of EEG beta band in the both hemispheres. Obtained data may indicate various origin mechanisms of paroxysmal states or neurotic condition (panic disorder) and psychosomatic (paroxysmal atrial fibrillation).
