In recent years, there has been a dramatic proliferation of research concerned with heart rate variability (HRV) analysis. Heart rate variability (HRV) analysis is a largely used method for accessing cardiac autonomic control. Based on HRV, the standard deviation of normal-to-normal (SDNN) heart beats and the ratio of low frequency (LF) and high frequency (HF) power of RR intervals can be used for...
Previous literature has suggested that psychological state may be changed via drinking coke, however, studies empirically documenting the link between coke and blood pressure wave (BPW) are scant. Therefore, the current article attempts to explore how coke intervene the mental condition with the assessment of pulse signal recordings. The quantitative analysis of the data was conducted through SAS,...
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...
This case study centered on the effects of Music Therapy (MT) on vegetative state (VS) patients for a continuous 41-day experiment with electrocardiogram (ECG) recorded. Mahler's Second Symphony was used for this MT. There are various elements in Mahler's second symphony, with string, wind, drum, and even voice; providing the subject a strong and dynamic stimulation. There are some significant changes...
How the musical tempo affects the performance of heart rate variability (HRV) was studied in this work. By understanding the relationship between the HRV response and the music tempo with decreasing tempo from 140 to 70 beats per minute (bpm) periodically in six successive weeks. There were two groups in the experiment, one was listening drum loop music 3 minutes in the middle of experiment and the...
This paper studies how the musical-rhythmic features affect the performance of heart rate variability (HRV). A physiological valence/arousal model of such a relationship is proposed. A systematic experiment was performed, subjecting human subjects to four different drum loops, in which was tried to define a set of rhythmic features (and ‘factors’) that could be correlated with the observed HRV readings...
The measurement of Heart rate variability (HRV) is a widely used and non-invasive method to assess the status of autonomic nervous system (ANS) and circulatory system. We try to find out the relation between two aspects: R-R intervals analysis on time domain (SDNN, RMSSD) and frequency domain (low and high frequency components), which shows the correlations between autonomic nervous system (ANS) and...
Previous literature has suggested that consciousness of patients in vegetative state (VS) may be enhanced via music listening; however, studies empirically documenting the link among music, vegetative state, and electrocardiogram (ECG) are scant. Therefore, the current article attempts to explore how music improves the VS patient's condition with the assessment of ECG recordings. The present work...
Healthcare issues arose from population aging. Meanwhile, electrocardiogram (ECG) is a powerful measurement tool. The first step of ECG is to detect QRS complexes. A state-of-the-art QRS detection algorithm was modified and implemented. By the dedicated architecture design, the novel ASIC is proposed with 2.21 μW power consumption and 0.68mm2 core area. It is the smallest QRS detection ASIC so far...
Heart rate variability (HRV) is a measure of variation in the heart rate. Over the last 25 years, HRV analysis has became utilized more often as a non-invasive research and clinical tool for indirectly investigating both cardiac and autonomic nervous system (ANS) functions in health and disease. In our experiment, 22 healthy subjects and four testing rhythm patterns are studied. How the three musical-rhythmic...
