碩士 === 國立交通大學 === 電機與控制工程系所 === 96 === Heart rate variability (HRV) is a measure of variations in the heat rate. Over the last 25 years, HRV analysis has became more and more popular as a non-invasive research and clinical tool for indirectly investigating both cardiac and autonomic nervous system (ANS) function in both health and disease area. It is choused as the physiological indicator for observing musical effect on ANS modulation. In this study, the concept of two musical rhythmic features, tempo and complexity, modulating human ANS is proposed. The main findings in this work are as follows. The rhythm pattern with faster tempo and lower complexity is observed to decrease the LF/HF and SDNN measure significantly in the resting period after the loop listening rather than the stable resting state. In the hardware implementation part, a high accuracy and low cost QRS detector SoC is realized. By understanding the relationship between music and the function of ANS, we can improve our life and health by music – non-invasively and simply.
