Abstract

Heart rate variability (HRV) and music have been demonstrated to have a relationship in previous literature. The primary objective of this study is to further investigate that relationship by observing HRV during periods of listening to relaxing and exciting music and comparing the results to a baseline as well as the other condition. The secondary objective of this study is to investigate the efficacy and potential usage of the Polar H10 chest strap monitor in measuring HRV parameters. The results of the Polar H10 will be compared to the iWorx TA-220 and iWorx-ECG12, the existing gold standard in HRV and ECG recording. The data will be exported to Matlab and Excel and analyzed to see if particular types of music display any trends for these HRV parameters, as well as heart rate (HR). Polar data will be gathered and analyzed using the EliteHRV app. Analysis included Fast Fourier Transform (FFT), Low Frequency/High Frequency Ratio (LF/HF), standard deviation of NN intervals (SDNN). Data was gathered in 10 minute intervals of No Music, Relaxing Music, Exciting Music. Results showed notable changes in LF/HF ratio in both directions. SDNN and Mean RR interval had moderate decreases in both relaxing and exciting music, with Total Power having a significant decrease in both. Comparison of Polar H10 and iWorx-ECG data showed strong agreement in heart rate and RR interval data, but significant differences in other data. This suggests differences in calculation by the software used.
