Chest vs. Heart issue?
I don't have any pain radiation down my arm/back/neck etc. its just around the left chest area. I do feel heart palpitations, though that might be anxiety induced...
How do i know its not a heart issue as opposed to some kind of muscle/skeletal irritation? I know my age profile doesn't fit someone with heart issues, but just wondering to be safe.
Separately, my resting heart rate is usually about 70 but can jump to 90-100 when just i stand up to move around. is that normal?
