[Psychoautonomic disorders in patients with neurocirculatory dystonia and the mitral valve prolapse syndrome].

Pattern was studied of autonomic regulation of cardiac activity in young male adults with mitral valve prolapse (MVP) versus patients with cardiac type of neurocirculatory dystonia (NCD). In assessing the condition of the autonomic nervous system we employed statistical analysis of heart rate at rest (vegetative tone) and at minute 60 of the intake of propranolol (vegetative reactivity). The patient's psychological state was assessed by MMPI. MVP patients had normal vegetative homeostasis but hyperreactivity of the autonomic nervous system in acute propranolol test; symptomatic patients displayed paradoxical reactions. NCD patients showed sympatheticotonia in rest and normoreactivity in acute propranolol test. We conclude that above patient populations experienced notable changes in their mental condition that reflect disturbances in the personality formation process.
