[Disorders in the regulation of blood pressure and heart rate as as expression of the autonomic neuropathy in diabetes mellitus].

In 30 diabetics with a peripheral neuropathy in comparison to a control group corresponding to age analyses of the circulation with continuous registration of the mean arterial pressure, of the heart and respiration rate were performed. For the objectivation of decreased waves of heart rate and blood pressure of 2nd and 3rd degree a spectral-analytic examination was additionally performed. The judgment of autonomous disturbances of regulation was made in every patient with the help of 10 functional parameters. No references to an autonomous neuropathy were found only in 2 patients, 1 to 4 pathological test results could be proved in 19 diabetics, and 5 to 9 pathological test results in 9 diabetics. A decreased respiratory arrhythmia in the stroke respiration and the absence of heart rate waves of 3rd degree in younger patients proved as particularly evident for the diagnosis of autonomous neuropathy. The present results of the examination refer to the fact that the inclusion of the complex examination methods using dynamic and rhythmologic functional parameters for the ascertainment of the diagnosis and for the graduation of the autonomous diabetic neuropathy is necessary.
