Autonomic nervous system diseases can cause abnormalities in the circulatory system, leading to malignant arrhythmia and sudden cardiac death. Standardized, operable, and simplified diagnostic indicators are urgently needed to evaluate autonomic nervous function, particularly cardiac autonomic nervous function. The investigators use HUTT in order to provide data support for cardiac autonomic nervous system evaluation.
In this study, 169 samples with vertical tilt test and 24-h Holter ECG data from February 13, 2023 to October 31, 2023 were selected. The AC, DC, and 24-h HRV were compared with the CASS to identify the indicators with the strongest correlation with the CASS sympathetic and vagus nerve scores. The best index was selected, and the score intervals were delimited. The sensitivity and specificity of the defined vagal and sympathetic intervals were analyzed.
108 studies on the registry are indexed under Autonomic Nervous System Diseases; 29 are open to participants now.
This study's planned enrollment of 1,122 is above the median of 69 across 34 observational studies indexed under Autonomic Nervous System Diseases.

To find the indicators which are most correlated to the sympathetic and vagus nerves.
The investigators use HUTT and CASS score to find some indicators which are most correlated to the sympathetic and vagus nerves,so that can give data support to the clinical treatments
