Effect of Slow and Fast Music on the Autonomic Nervous System and Cardiac Health

In this study, the effect of slow and fast music on the heart rate variability and conduction pathway of the heart was studied. The results indicated an increase in the parasympathetic dominance as the volunteers were made to listen to music. The magnitude of the parasympathetic activity was higher when the volunteers were made to listen to fast music. This indicates that slow and fast music affected the sympatho-vagal balance in different proportions. The analysis of the ECG signal and wavelet transformed ECG signal suggested an alteration in the conduction pathway of the heart.
