I've been having bad panic attacks and anxiety over my heart this past month and I had an ECG which was healthy.

But I'm still worried that my heart goes up way too much after very minimal exercise.

I just walked down and up 7 stairs and my heart rate went from 100 to 137


Now to be fair I am mid panic so idk if that changes it???

I'm just scared because before the panics I never really felt like this before.

Another thing that scared or triggered this was sitting iny car after standing up for 5 hours.

I got to my car off work and sat in my car and I noticed my heart felt a little too fast. It was like 100-110 but I kinda started to panic. And then I went to a store and drove home and still continued to panic.

It's been 1.5 hours since the start and my heart's still around 110. I had that ECG that said I was fine.

But very little exercise feels like it stirs up my heart a lot. From standing to going down and up 7 stairs it goes from 100 to 137 and I did it twice.

My mom and brother did it twice too and my mom went from 85 to 95 and my brother went from 95 to 105.

Did my heart really go bad over this month is is it like overly sensitive to stress and could this be caused by anxiety and panic?
