[Autonomic innervation of the heart of young XXXX with @entity1723 ].

@entity1 @entity1164 @entity6 @entity9765 @entity3949 @entity1723 @entity3897
The autonomic innervation of the heart has been studied in 32 young @entity1 with @entity1723 and 28 controls by measuring the intervals PP of electrocardiograms at rest, deep breathing, stimulation of n. vagus according to Ashner method and after suppression of vagus tone by @entity3897 . The orthostatic test was performed. The @entity1 with @entity6 were established to have a higher heart rate and less manifested variations of the intervals PP at rest. During deep breathing, the @entity1 with @entity6 also showed a poorer variability of the intervals PP as compared with the controls. The reactions, however, in both groups with Ashner test and orthostatic test, were similar. Asymptomatic @entity9765 was recorded in a @entity1 with @entity6 by the method of Ashner. The study revealed that the autonomic innervation of the heart was oft disturbed in case of @entity6 . There was a correlation between the severity of that disorder and @entity6 duration, @entity3949 established in all cases. The other manifestations of @entity3949 are more rare and later observed. The disturbed autonomic innervation of heart activity could be responsible, in some cases, for the @entity1164 among the @entity1 with @entity6 .
