sunus arrythmia when breathing?

[joshua77]

What does this mean when you breath in and out heart rate changes

[itdood]

p.s., should say  O2 uptake and CO2 release.

[itdood]

Nature evolved it to improve O2 absorption.  When you breath in, HR speeds up to pump more blood (into the lungs) for the fresh air.  As we breath out (exhale, HR will slow down, which slows the blood flow through the lungs.

This improves blood/gas exchange. As we age it gets less pronounced,  I'm 45 and still have it.
