The air becomes thinner so less oxygen in every heart beat so to keep up the oxygen it has to beat faster

the heartbeat is controlled by the brain.Until that dies from oxygen starvation the heart will continue to beat
No
Every Beat of My Heart - Rod Stewart album - was created on 1986-06-23.
beacuse you'er heart needs to pump so the body can get blood and oxygen
A heart will beat for a little while until your brain shuts down.
When you are working hard, it will beat faster to get oxygen to the body more quickly. When resting, it will beat more slowly.
Electrocardiograms are taken when doctors need to check on the hearts rhythm, and the conduction of the heart beat which might be caused by a underlying heart disease.
Because the heart has to pump more oxygen than usual to your muscles
- Muscles require oxygen to function - When running, you are working muscles - Blood carries oxygen, the heart pumps blood When running, as the muscles require more oxygen to work harder, the heart must pump blood around your body quicker, delivering more oxygen to the muscles that require it. The way that the heart does this is to increase heart rate.
When you exert, the cells need more oxygen. The heart delivers blood that carries oxygen, so as the demand for oxygen increases the heart rate (and the volume of blood delivered on each beat) increases.
