I’m an ED nurse and I work part time 12 hour shifts (2 shifts twice a week)
I noticed that my HR all day is above 110. Usually between 110-130. As an ED nurse I’m on my feet pretty much all day.

I have POTS + I’m 26 weeks pregnant so my HR is naturally gonna be high when I’m standing.
I noticed I’m getting sporadic adrenaline dumps at work and my HR will shoot up too.

I’m just worried that I’m straining my heart with it being so elevated pretty much all day at work.

When I’m home resting it’s usually 80s.

Any advice?
