[Impairment of cardiac autonomic nervous system and incidence of arrhythmias in severe hyperglycemia].

Background And Purpose: Deterioration of cardiac autonomic nervous system in diabetics is associated with increased cardiac and arrhythmogenic mortality. Therefore, the present study engaged in the question how heart rate variability is acutely changed in diabetic ketoacidosis or hyperglycemic hyperosmolar syndrome. Moreover was evaluated how blood pressure, heart rate and incidence of arrhythmias can be explained by figures of heart rate variability.

[Continuous analysis of heart rate variability for examination of cardiac autonomic nervous system after alcohol intoxication].

Background: Alcohol intoxication is associated with deterioration of cardiac nervous function and increased mortality.

Patients And Methods: Therefore, 14 patients (eight male, six female; 24-59 years) with pure ethanol intoxication and toxic levels of 210-520 mg/dl in the blood were prospectively investigated. For evaluation of changes in sympathetic and vagal modulation, an analysis of heart rate variability (HRV) was performed.
