Abstract
|
|
|
Background: Standardized autonomic function test has become widely available. However, there is no reference data in Korean population. This study explored the reference data for sudomotor and cardiovagal study in Korean population.
Methods: Quantitative sudomotor axon reflex test, heart rate difference to deep breathing (HRdb), expiratory: inspiratory (E:I) ratio and valsalva ratio (VR) were measured in 300 healthy Korean volunteers aged from 19 to 78 years. Multivariate regression analysis was done to evaluate the effect of age, sex and body mass index. 2.5th, 5th, 10th, 90th, 95th, and 97.5th percentile values were obtained for each study.
Results: Sweat volume was higher in males than in females. HRdb and E:I ratio were inversely related to age and were higher in males than in females. VR was inversely related to age but was not related to sex.
Conclusions: This study provided the reference range of sudomotor and cardiovagal function study in Korean healthy adults.
