碩士 === 國立成功大學 === 航空太空工程學系 === 104 === Non-Invasive Hemodynamic Analyzer (NIHD) use condenser microphone for mearsuring the rudimentary data at the wrist radial artery. The acoustic signal contains some information of the cardiovascular system and other physiological conditions. The purpose of this research is dismantling the signal which collected from heart valve diseases patients, and find the feature from their data. I model it by Yule-Walker method, then try to find the relationship between spectral characteristic and different kinds of valve diseases. At last, results of statistics shows that when patients’ heart valve insufficiency is more severer, the characteristics of waveform is more easier to be analyzed. Non-Invasive Hemodynamic Analyzer operate simply and make interpretation easily. It can be used to assist in clinical primary care staff for valvular heart disease simple preliminary assessment, even ordinary people in everyday life self-test.
