title: [Autonomic regulation of cardiac activity in patients with ischemic heart disease and neurocirculatory dystonia: asymmetry of cardiac rhythmograms].
abstract: Thirty-six males with the cardiologic syndrome were examined to compare the autonomic regulation of cardiac performance in patients with coronary heart disease and neurocirculatory dystonia. The standard analysis of autonomic specimens indicated a relative reduction in a response of the parasympathetic link of the autonomic nervous system in patients with coronary heart disease than in those with neurocirculatory dystonia. A new approach was proposed to analyze the specimens with deep slow respiration, which included the construction of rhythmograms, followed by the determination of an asymmetry coefficient and a reduction index. Patients with coronary heart disease were found to have an asymmetric rhythmogram while those with neurocirculatory dystonia had a symmetric one.
