I am 21 yrs old. So recently my cardiophobia has gotten worse and I'd like some reassurance if anyone can provide any.
So my sleeping heart rate averages low 50s, when I sit it ranges from 50-80 and when I'm walking around it is 80-110 depending.
My concern is that it gets too low when I sleep.
I live a sedentary lifestyle and so I am not active or fit at all. I've had ecgs, holter monitor, echo and stress test done last year and the results came back fine. My BP is also normal. I also have no history of heart problems, besides palpitations.
However last year, my rhr was higher than it was this year. I'm scared that it will go even lower when I sleep, I have had an instance where my apple watch notified me that my hr dipped to 34 once when I was sleeping earlier this year.
When I lie down after standing up, my hr slows down really fast as well.
I also used to have constant palpitations where I can also feel my heart beating in my chest, but now I have to really focus to feel it beating.
I'm just wondering why my hr is so slow, since normal resting hr is between 60-100, when I'm not active at all. Should I be worried? And is having an echocardiogram good for detecting any possible heart problems? Since I got it done last year and doctor said everything is okay, should I get another one this year?
