Key result
Listening to music, compared with silence, transiently increased the bandwidth of polarization and depolarization of heart rate and the amplitude of the T wave.
Why the study?
Does listening to different types of music alter ECG parameters compared to silence?
Does listening to different types of music alter ECG parameters compared to silence?
Listening to music, particularly arousal music, transiently alters ECG parameters such as T wave amplitude and polarization/depolarization bandwidth compared to silence.

Transient ECG changes with music should not alter practice; leaves open arrhythmic risk implications.
In this paper heart feature changing which is taken from electrocardiogram (ECG signals) during three stages will be compared with each other. These stages include listening to sedative music, arousal music and a period of complete silence. Observation shows that amplitude of polarization and depolarization can change when different kinds of music are heard. Without considering the type of music, hearing a sound makes heart to beats differently from the silence. Each kind of music influences on heart in different way for instance arousal music effect on the maximum of the T wave whereas the sedative music does not. The results imply that the bandwidth of polarization and depolarization of heart rate and amplitude of T wave is increased when music is heard in contrast with silence and finally sound have transit effect on the heart and not stable effect.

Dousty et al. (2010) studied this question. Listening to sedative and arousal music vs. Complete silence was evaluated on ECG signal changes (amplitude of polarization and depolarization, T wave maximum). Listening to music, compared with silence, transiently increased the bandwidth of polarization and depolarization of heart rate and the amplitude of the T wave.
