Study on Evaluation Model of Activity and Balance of Autonomic Nervous System Based on AHP

Abstract

The abnormal parameters reflecting the functional status of autonomic nerve can be regarded as a marker of cardiovascular diseases prognosis. Then based on the analytic hierarchy process, this paper proposed a quantitative evaluation method of autonomic nervous system activity and balance. According to the hierarchy analysis, heart rate variability parameters are divided into time domain parameters, frequency domain parameters, nonlinear parameters. The judgment matrix is constructed according to the relative importance of each index, then the weight of each index is calculated. The consistency test verifies the reliability of the judgment matrix. The results showed that with the increase of stimulation level, sympathetic nerve activity increased, and parasympathetic nerve activity decreased. The balance of sympathetic and parasympathetic increased. It showed that this model can reflect the change of autonomic nervous system, and has certain theoretical research value.
