the Sino Atrial Node (SA Node) is the pace maker of the heart that receives singles from the brain.
Hypothalamus control your heart rate. Medulla oblonga;ta assists in the control of breathing

Heart beat
The heart controls the heart beat and the lungs control breathing
If I do not recall, Is it Hitchcock?
The only way I can think that music would affect the heart beat! is by increasing the amount of the hormone adrenalin secreted by the pituitary gland. Andrenalin control the pacemaker cells of the heart and regulates the heart beat. So if there is more adrenalin, the heart beat would go faster. The same would occur with Coffee/Caffeine.
Yes
no beat the elite four first
Normally this would not occur. Beats between regularly spaced beats are called premature contractions and can occur with either the top or bottom chambers of the heart. This has the potential for causing an irregular heartbeat called an arrhythmia.
Your heart would not beat in a regular pattern. The pacemaker (the natural one) is there to control the beat of your heart which is why when you run your heart beat gets faster to pump more blood around the body. If you do not have one then your heart beat wont beat fast enough if your running or maybe not fast enough at all. That is even if it beats at all>
