[Clinical functional aspects of cardiac activity and vegetative imbalance in dumping syndrome]

Programmed computer transesophageal pacing with pharmacological heart denervation by A. Jose and D. Collinson, mathematical analysis of cardiac rhythm according to spectral and statistical methods were used in the study of extra-abdominal (cardial and vegetative) manifestations of dumping syndrome (DS)--one of severe complications of ulcer surgery. Serotoninemia was assessed by enzyme immunoassay (DRG kit). It was established that cardial and vegetative disorders are typical for DS patients and correlate with severity of motor defects of the gastrointestinal zone as well as fasting serotonin levels. Cardiac arrhythmias in DS in most cases are associated with functional insufficiency of pacemakers. This requires caution in administration of antiarrhythmic drugs in DS patients.
