The effect of different kind of music and silences on electrical heart working

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.
