Musical Listening

University students ( N = 30) individually listened to the Billboard 100 top-ranked musical selection for their most and least liked musical genre. Two minutes of silence preceded each musical listening condition, and heart rate variability (HRV) was recorded throughout. All HRV measures decreased during music listening as compared with silence. Dependent t-tests found significant decreases for beats per minute ( p < .01, like; p < .001, dislike) and low frequency ( p < .01, like; p < .05, dislike). A significant decrease in low-frequency/high-frequency ratio ( p < .05) was found for the dislike–music listening condition. A sign test showed no significant difference in the number of mean readings that increased or decreased for either music listening condition. Findings may support previous research that HRV decreases during mentally engaging tasks but may not support previous research that HRV readings could be a measure of emotional responding.

Sympathovagal modulation during immersion in a virtual environment is an important influence on human performance of a task. The aim of this study is to investigate sympathovagal modulation using heart rate variability and perceived exertion during exercise in a virtual reality (VR) environment. Sixteen young healthy volunteers were tested while using a stationary bicycle and maintained at an anaerobic threshold intensity for exercise sessions of approximately 10 min duration. Four randomized viewing alternatives were provided including desktop monitor, projector, head mounted device (HMD), and no simulation display. The “no simulation display” served as the control group. A quick ramp exercise test was conducted and maintained at an anaerobic threshold intensity for each session to evaluate power spectral density and rating of perceived exertion (RPE). The sampled heart rate data were rearranged by cubic spline interpolation into power spectrums spanning the ultra-low frequency (ULF) to high frequency (HF) range. A significant difference was found between the no-display and projector groups for total power (TP) and very low frequency (VLF) components. In particular, there was a significant difference when comparing HMD and no-display exercise RPE curves within 6 min of cycling and at the termination of the exercise. A significant difference was also achieved in projector vs. control group comparison at the termination of the exercise. Our results indicate that the use of HMD and the projected VR during cycling can reduce the TP and VLF power spectral density through a proposed decrease in the renin-angiotensin system, with the implication that this humoral effect may enable anaerobic exercise for longer durations through a reduction in sympathetic tone and subsequent increased blood flow to the muscles.

The aim of our study is to measure very low frequency band (VLF), low frequency band (LF) and high frequency band (HF) components of R-R interval during orthostatic experiment in panic disorder patients before and after treatment.MethodsWe assessed heart rate variability in 19 patients with panic disorder before and after 6-weeks treatment with antidepressants combined with CBT and 18 healthy controls. They were regularly assessed on the CGI, BAI and BDI. Heart rate variability was assessed during 5 min standing, 5 min supine and 5 min standing positions before and after the treatment. Power spectra were computed using a fast Fourier transformation for very low frequency - VLF (0.0033 - 0.04 Hz), low-frequency - LF (0.04-0.15 Hz) and high frequency - HF (0.15-0.40 Hz) powers.Results19 panic disorder patients entered a 6-week open-label treatment study with combination of SSRI and cognitive behavioral therapy. A combination of CBT and pharmacotherapy proved to be the effective treatment of patients. They significantly improved in all rating scales. There were highly statistical significant differences between panic patients and control group in all components of power spectral analysis in 2nd and in two component of 3rd (LF and HF in standing) positions. There was also statistically significant difference between these two groups in LF/HF ratio in supine position (2nd). During therapy there was tendency to increasing values in all three positions in components of HRV power spectra, but there was only statistically significant increasing in HF1 component.Supported by project IGA MZ ČR NS 10301-3/2009

This study identifies a correlation between low-frequency heart rate variability (LF-HRV) and encephalographic (EEG) complexity to differentiate internally operative attention (INT) and externally operative attention (EXT). Electrophysiological fluctuations in response to Posner’s spatial orienting paradigm were explored in 14 healthy volunteers who participated in 6 alternating sessions of attention tasks. HRV analysis was used to measure heart rate fluctuations, and approximate entropy (ApEn) was used to measure changes in the irregularity of EEG and HRV. Power spectral analysis of HRV revealed that there was found to be a significant difference between INT and EXT for HRV-low frequency (HRV-LF) and LH/HF ratio. ApEn for RR-interval time series increased for both attention tasks as compared to baseline and recovery session. The relationship between HRV-LF and EEG spectral power measured at F4 revealed significant negative correlation during ([Formula: see text], with [Formula: see text]) EXT than ([Formula: see text], with [Formula: see text]) INT. Furthermore, a significant positive correlation, yet of moderate strength was noted between HRV-LF and ApEn of EEG signal measured at POz ([Formula: see text], with [Formula: see text]) during EXT as compared to INT ([Formula: see text], with [Formula: see text]) and, a significant negative correlation was observed between ApEn of RR-interval and ApEn of EEG signal measured at POz ([Formula: see text], with [Formula: see text]) during EXT as compared to INT ([Formula: see text], with [Formula: see text]). Thus, it is evident that EXT leads to more irregularity in parietal regions of the brain than the INT. During EXT, the irregularity over the parietal region linked to increased sympathetic activity as compared to INT and corresponds to decreased heart rate. These results may benefit in designing robust human-computer interfaces and accelerated training paradigm to raise an athlete’s performance.

Abstract Background We investigated the relationship between psychological distress and the coordination of heart rate variability (HRV) and physical acceleration (PA) during free-moving days in women. Methods Ninety-five adult women were divided into younger and older groups. The younger group comprised 50 women (22–59 years), and the older group comprised 45 women (≥ 60 years). HRV and PA data were simultaneously obtained every minute for 24 h during the free-moving day. The ratios of low frequency/high frequency and high frequency in normalized units were used as HRV indices. We defined %Lag0 as the % frequency of the lag = 0 min between HRV and PA in 1 h. The General Health Questionnaire 28 (GHQ28) was used to evaluate the effects of psychological distress and depression. Results In the hour before the night’s sleep, %Lag0 was significantly lower in older women with depression (GHQ28 subscale D) than in older women without depression (p < 0.05). However, no significant difference between %Lag0 and depression status was observed in the hour after waking in older women. Conclusions The results suggest that impairments in coordination between HRV and PA are associated with depression in older women, particularly in the hour before a night’s sleep on free-moving days.

Objective: Stress of working conditions change the circadian rhythm and body’s autonomic functions. Heart rate variability is a simple and noninvasive method that reflects the heart’s autonomic system. In this study, we analyzed the rhythm differences of intensive care unit nurses between 24 hours shift and rest days. Materials and Methods: 51 nurses working in intensive care units of our center were included in the study. The nurses were divided into two groups as study and control groups according to the shift and rest days for 24 hours holter recordings, respectively. Results: Heart rate parameters were under parasympathic and sympathic dominance in rest and shift days, respectively. Although normalized high frequency, normalized low frequency and low frequency/high frequency ratio values were parallel to the shift and rest days at 24-hour intervals, inverse correlations were observed between 03.00- 08.00 hours. No statistically significant difference was seen in circadian rhythm between shift and rest days. Heart rate parameters generally showed similar pattern of circadian rhythm irrespective of the working status of the participants. Sympathetic activity was significantly higher in the day period than the night period in the shift days however there was no difference within resting group. Conclusion: Slight increase in sympathetic system activity and marked decrease in parasympathetic activity during 03-05 o’clock were apparent in shift days. This increase was attributed to early cortisol release.

This study aimed to determine whether heart rate variability (HRV) can express the thermal comfort of mine workers. Eight subjects ran on a treadmill (5.5 km/h) to simulate heavy labor in three kinds of mining environments (22 °C/90%, 26 °C/90%, 30 °C/90%), respectively. Based on the measured electrocardiogram (ECG) data, the HRV of the subjects was calculated. The results showed that the HRV indices changed obviously under different temperature environments. In the neutral and hot environment, except for the LF, TP and LF/HF, there were significant differences in each index. However, there was no significant difference between the cold and neutral environments. The R-R intervals, the very low-frequency power (VLF), pNN20 and SampEN had strong negative correlation with the thermal sensation of people from sitting to work (ρ < −0.700). These indices may be used as thermal comfort predictive biomarkers of mine workers.

Abstract Background: Music and music therapy, live or recorded, has been gradually introduced in the Neonatal Intensive Care Unit (NICU) of our Hospital in addition to standard medical and nursing care, to improve premature neonates’ neurophysiological development. The present study focused on music genres, starting from the parents’ sound experience and musical tastes that neonates experienced during the pregnancy period. The study explored the effects of different music genres also on Extremely Low Birth Weight (ELBW) neonates since most studies refer to Very Low Birth Weight (VLBW) neonates with birth weight > 1000 gr. The study aims to investigate the influence of different music genres on Heart Rate Variability (HRV) of preterm neonates.Methods: a prospective randomized study was conducted. Preterm neonates (gestational age <32 weeks, birth weight <1500g), were recruited. On the basis of birth order, they underwent a daily randomized music listening program (25 minutes, every day, for 3 days) based on different music genres listening (soft pop-rap, pop-rock and classical music), followed by 1 day of no music monitoring (25 minutes). An electrocardiogram was performed to evaluate HRV parameters in each neonate with and without music exposure.Results: twenty-seven (13 ELBW, birthweight <1000 g and 14 VLBW, birthweight 1000-1500 g) infants were included and HRV parameters were analysed. In the VLBW group no significant results were found between the music genres. In the ELBW group, during Soft Pop-Rap music listening, starting after 5 minutes High Frequency (HF) increase significantly (HF P =0.0096) and Low Frequency (LF) and LF/HF indices decrease significantly (LF P= 0.0096; LF/HF P=0.0068). The same trend was from 15 minutes of music listening high frequency (HF) increased and low frequency (LF) decreased (LF P=0.007; HF P= 0.007), Consequently LF/HF also decreased significantly (LF/HF P = 0.0093).Conclusion: A significant decrease in the activity of the sympathetic and a simultaneous increase of the parasympathetic nervous system were found in the ELBW group during Soft Pop-Rap music listening. Further studies with a larger sample size are needed to confirm these findings and to elucidate the underlying mechanisms.Trial registration: ClinicalTrials.gov Identifier: NCT04049526 The Effects of different music genres on heart rate variability in extremely and very low birth weight new-borns.

Background: In chronic kidney disease (CKD) patients, decreased heart rate variability (HRV) reflects impaired cardiac automatic nervous function and high risk of cardiovascular disease (CVD). Lower HRV in patients with severe secondary hyperparathyroidism (SHPT), a clinical manifestation of CKD-mineral and bone disorder (CKD-MBD), could be reversed by parathyroidectomy (PTX). It has been proved that leptin interacts with the autonomic nervous function. However, the associations between leptin and HRV in CKD patients and their longitudinal changes in SHPT patients after PTX are still unknown. Methods: This was a cross-sectional study including 141 stage 5 CKD patients, and a prospective study in 36 severe SHPT patients with PTX. HRV was measured by Holter and serum leptin was measured by ELISA. Serum leptin levels were adjusted for body mass index (BMI) and transformed using natural logarithm (lnleptin/BMI). Results: With a gradient of lnleptin/BMI across quartiles from Q1 to Q4 in CKD patients, HRV indices showed no differences among quartiles. Patients in Q1 group had higher mean 24 h heart rates, and lower ln(very low frequency) (lnVLF) than other quartiles, although there were no statistically significant difference. In multivariate stepwise regression, serum leptin/BMI was an independent predictor for low frequency/high frequency. HRV indices and lnleptin/BMI levels were increased in severe SHPT patients after PTX. Compared to other quartiles, SHPT patients in Q1 group had larger improvement of lnVLF after PTX. Conclusion: Circulating leptin levels may be a novel treatment target to reduce CVD risk in advanced CKD-MBD patients.

Background: Tuberculosis is major cause of death in India. Analysis of heart rate variability is one of the most popular methods of autonomic nervous system evaluation. Shorter MDR-TB regimen drugs affect both central nervous system as well as peripheral nervous system. Existing research suggests that active pulmonary tuberculosis causes ANS dysfunction. So, by HRV measurement impact of shorter MDR-TB regimen drugs on autonomic dysfunction can be correlated. Aim of the current investigation was to evaluate effect of shorter MDR-TB regimen drugs on cardiac autonomic regulation in MDR-TB patients with respect to heart rate variability as a parameter.Methods: Fifty newly diagnosed MDR-TB patients of either gender on shorter MDR- TB regimen were enrolled in this study after taking consent. After 20 minutes rest, ECG was taken by “physiopac digital polygraph” software for 5 minutes. Two follow-up HRV assessments were done on 2nd month and 4th or 6th month of treatment. HRV was calculated by root mean square deviation of successive differences between adjacent RR intervals (RMSSD) and low frequency and high frequency ratio.Results: Repeated measures ANOVA showed no statistically significant difference in HRV parameters between baseline, 2 months and 6 months groups. So, sympathetic and parasympathetic modulation in terms of HRV remains unchanged during treatment of MDR-TB with shorter MDR-TB regimen drugs.Conclusions: Shorter MDR-TB regimen drugs don’t have any significant impact on HRV in MDR- TB patients, No correlation was observed between HRV and heart rate in MDR-TB patients.

Abstract Depression associates closely with autonomic nervous system and physical activity, however, there have been no studies on the relationship between depression and the coordination of heart rate variability (HRV) and physical acceleration (PA). Ninety-five adult women were divided into non-older and older groups. The non-older group comprised 50 adulte women (below 60 years), and the older group comprised 45 women (above 60 years). HRV and PA data were simultaneously obtained every minute for 24 h during the free-moving day by using the ActiveTracer accelerometer. The ratios of low frequency/high frequency and high frequency were used as HRV indices, indicating sympathetic and parasympathetic nervous activities, respectively. Lag time was determined as the time difference indicated by the maximum absolute cross-correlation coefficients obtained from the analysis between the HRV components and the PA. We defined %Lag0 as the % frequency of the lag = 0 min between HRV and PA in 1 h. The General Health Questionnaire 28 (GHQ28) was used to evaluate the effects of psychological distress, including depression. In the hour before the night’s sleep, %Lag0 was significantly lower in older women with depression (GHQ28 subscale D) than in older women without depression (p <0.05). However, no significant difference between %Lag0 and depression status was observed in the hour after waking in older women. The results suggest that impairments in coordination between HRV and PA are associated with depression in older women, particularly in the hour before a night’s sleep on free-moving days.
