“…Unexpectedly, SDNN decreased during the listening period of Thai classical music, which is considered sedative music. This finding aligns with a study conducted by Plassa et al (2014), which showed that classical baroque music decreased SDNN in the group that enjoyed the music (Plassa et al, 2014). In this study, the decrease in SDNN may be attributed to a reduction in parasympathetic activity, as shown by the reductions in RMSSD and PNN50.…”

Relaxing music, such as classical music, could improve autonomic nervous system function by reducing sympathetic activity and increasing parasympathetic activity, as indicated by an increase in heart rate variability (HRV). However, it is unknown whether Thai classical music, which is considered to be relaxing music, could induce autonomic alterations. This study investigated the effects of classical, heavy metal, and Thai classical music on cardiac autonomic activity, as determined by HRV, using a crossover design methodology. All subjects were exposed to the three music stimulations. Electrocardiograms (ECGs) were recorded before, during, and after music listening. The results showed that the standard deviation of normal-to-normal R-R intervals (SDNN) and low frequency (LF) power were significantly decreased during listening to Thai classical music. The decreased SDNN might be due to a reduction in parasympathetic activity, as indicated by the reduction in root mean square successive difference (RMSSD) and percentage of subsequent R-R intervals with a duration difference longer than 50 ms (PNN50). However, the decrease in parasympathetic activity was not large enough to induce autonomic imbalance as shown by an insignificant change in high frequency (HF) power. A positive correlation between LF power and HF power was also observed during listening to Thai classical music. This suggests that HF power functioned to counterbalance the change in LF power during the listening session. In conclusion, only Thai classical music affected cardiac autonomic function by decreasing sympathetic activity without altering cardiac autonomic balance.

“…37 The physiological and psychological influence has been suggested as owing to the influences of hormones. 38,39 Therefore, this study is unique in that it has proved a mildly significant statistical difference between the control subjects and those under influence of heavy metal music. However, the differences which are significant where all three chaotic globals are applied, lead to an increase in the measurements of chaos.…”

OBJECTIVE:Auditory stimulation with relaxing style music can improve cardiac autonomic regulation in subjects treated with a cardio-toxic medication. We assess the acute effect of heavy metal music on cardiac autonomic regulation, through novel high spectral chaotic global analysis techniques: (a) high spectral detrended fluctuation, (b) high spectral entropy (c) spectral multi-taper method. METHOD: We investigated young adult women between 18 and 30 years old exposed to heavy metal (75-84 dB) music for 20 min. Normality tests were applied: (i) Anderson-Darling, (ii) Ryan-Joiner (similar to Shapiro-Wilk); (iii) Lilliefors for low number of subjects. They all indicated a non-normal data distribution. Consequently we applied the Kruskal-Wallis non-parametric test. Also because of the small population, we used a broader than usual level of significance (critical p = 0.1). RESULTS:The application of the three tests for normality and the non-parametric test of significance by the KruskalWallis technique showed that acute musical auditory stimulation with heavy metal music lead to a significant increase (p < 0.07) in one of the seven combinations of chaotic globals. The most significant combination of chaotic globals is the Chaos Forward Parameter One (CFP1), which includes all three studied chaotic globals (high spectral detrended fluctuation, high spectral entropy, spectral multi-taper method). We found significantly increased values during musical auditory stimulation for this specific CFP1. CONLCUSION: It is suggested that acute musical stimulation with heavy metal influences cardiac autonomic regulation at a more complex level than previously reported and that this may be beneficial to heart function.

“…According to Tulppo et al, 11 the sympathetic and parasympathetic components of the autonomic nervous system behave in a reciprocal manner, so that an increase in one of them leads to a decrease in the other.…”

OBJECTIVE:A previous study suggested that the p-value of normality test applied to RR intervals is an index able to quantify Heart Rate Variability (HRV) through correlation of traditional time and frequency domain indices. We investigate the association between the p-value of normality test applied in RR intervals and symbolic analysis of HRV. METHOD: We evaluated 32 healthy women between 18 and 30 years old. RR intervals were used for HRV analysis and we performed symbolic analysis, where RR intervals are joined by symbols. Sets of three consecutive symbols (RR intervals) were grouped into four types of clusters, as follows: 1. Three equal symbols (zero variation); 2: two equal, one divergent symbol (one variation); 3. Three different symbols monotonically ascending or descending (two like variations); 4. Three different symbols, forming a peak or a trough (two unlike variations). Frequency of occurrence of each type of cluster was calculated. Normality tests were applied to all RR intervals and the p-value was calculated. We computed the correlations between the p-value of normality test and symbolic analysis of HRV. RESULTS: Correlation coefficients between the p-value of normality test from Kolmorogov-Smirnov test and the four types of clusters showed no correlation for any of them. Likewise, the correlation coefficient index between the p-value of normality test calculated from the Shapiro-Wilk test and symbolic analysis produced no significant results for any of the four types of clusters. CONCLUSION: There was no significant correlation between the p-value of normality test and HRV symbolic analysis. The physiological significance of this result is that the PNT is not related to chaotic behavior of HRV.
