The coronavirus pneumonia (COVID-19) epidemic has a major global impact since 2019. So far, due to the continuous emergence of mutated strains of the virus, in addition to different clinical symptoms, the causes of disease and prognosis of infected patients are also different. With the rapid increase in the number of confirmed cases in Taiwan, we can see that there are many sequelae caused by the COVID-19. Although most of the infected patients can fully recover, some people have various medium and long-term symptoms, which are called Long COVID or Post COVID. In addition to causing lung tissue damage and inflammation, the COVID-19 also affects the digestive system, causing patients to experience symptoms such as diarrhea, vomiting, and loss of appetite; damages the nervous system, causing insomnia, poor memory, and loss of taste and smell; affects the kidneys function and cause edema, etc.; or even reduce the number of sperm cells in men, thereby affecting reproductive function. It can be seen clinically that some symptoms will last for a long time or appear repeatedly. These symptoms may be present at the time of initial infection, may appear after recovery, or recur over time, affecting the patient's daily life. From our study, it reveals that through the conditioning diagnosis and treatment of traditional Chinese medicine, the human body disorder after virus infection can be balanced as soon as possible and the health can be restored.~This research proposes to use pulse diagnosis instrument and cardiac rhythm instrument for disease diagnosis and analysis, decompose time domain pulse wave signal into time domain signals of different frequency ranges, and extract 0-10Hz low frequency wave, 0-50Hz global wave, 13-50 Hz high-frequency waveform calculates the spectral energy ratio (SER) and EP to quantify the patient's pathological pulse. Try to find the relationship between this set of parameters and clinical subjective scale scores. The analysis method proposed in this study has been applied to the pulse wave analysis of people with suboptimal health status (SHS), and its effectiveness has been preliminarily confirmed. Corresponding relationship with heart rate variability (heart rate variability, HRV) high and low frequency parameters, to further link the activation status of sympathetic nerve and parasympathetic nerve, and establish an objective data bridge for Chinese and Western medicine diagnosis. In the future, more subject data will be included to verify the completeness of the analysis method and establish a feasible prediction model.
