Study of the application of frequency matching and coherence effect between heart and arterial system on the diagnosis of Chinese
medicine
In previous research, we presented a novel idea for analyzing blood circulation that is viewed as an electrically-driven, mechanical-pumping mechanism. Considering the ECG and blood pressure wave (BPW) as the input and output signals of the system, we quantify the spectral behavior of blood circulation from the viewpoint of frequency matching (coupling coefficient) and coherence effect (coherence function). For present study, we
intend to apply these methods to the diagnosis of Chinese Medicine, and focus on the disease of liver problem.
Forty patients’BPWs and ECGs will be detected and classified into three categories according to the diagnosis of clinical doctor of Chinese medicine. On the other hand, we classify the patients according to the coupling coefficient and coherence function. Comparing the
classification results of the above two methods, we assess whether the coupling coefficient and coherence function can be applied in the diagnosis of Chinese Medicine.
