Hi Chris, some links to the principle of Respiratory Sinus Arrhythmia.

Respiratory sinus arrhythmia: why does the heartbeat synchronize with respiratory rhythm?

Sinus arrhythmia is very common in children but generally we grow out of it.  However, I have it and it is not at all a concern for doctors.  Your 10 beat difference is actually probably considered normal, mine can fluctuate 20 or even 30 when it is extreme.  If you start to become short of breath or have chest pain then go and see your doctor otherwise try to not fret about it.  It sounds like you are in good shape.

Thanks for your answer I have clocked that this varies throughout the day in the morning when I use it it stays a steady 55 to 60. Mainly in the evening it jumps around like a yo yo I'm 24 within my bmi and now doing 4 miles run

Also someone said the quicker your heart rate fulls after excerice the better you are

Hello,

Depending on your age or conditioning, there is an effect called Respiratory Sinus Arrhythmia. Years ago, my dog was laying on the floor, and I had my hand on his side. His heart rate was going faster and slower. After observing, I realized his heart rate fluctuated with his breathing. I already was familiar with the term Respiratory Sinus Arrhythmia and was unconcerned.

As we breathe in, our heart should increase in rate, as we breathe out, it should slow. It's most pronounced in children and adolescents and, I believe, may occur in conditioned adults as well.

Experiment with your monitor, take moderately deep breaths in, slowly, and watch the rate. Then slowly breath out and watch the rate.
