Removement of the three minutes irritating music produced no incremental relaxation

This paper studies how the incentive bass drum sound, or a simple fast rhythm affect the performance of HRV (Heart rate variability), which is a measurement of variations in the heart rate. We expect to find a relationship of music and human cardiovascular condition. Related experiments have been tested and got some results. Over the last 25 years, HRV analysis has become more popular and important as a non-invasive research of biomedical engineering. HRV is a widely used method to assess cardiac autonomic control. There are two important measures. The first one is SDNN, and the second one is LF/HF. Through the Fast Fourier Transform (FFT), the low frequency (LF) and high frequency (HF) power were obtained from NN intervals. LF/HF reflects the sympatho-vagal balance of autonomic nervous system (ANS). By understanding the relationship between the same tempo with different times of measuring in continuous weeks and the HRV information, we can improve our life and health. The music have some irritate to human cardiac, just like rock music. From the results of this experiment, we can expect to find the influence of this music type to human cardiovascular condition.
