Is this a normal testing heart rate?

Ok so I woke up really early this morning and got up to make some coffee, so I'm walking around for like 15 minutes. Anyway... The whole time my chest was feeling funny so I sit down and feel my pulse randomly out of curiosity. 46! Afture walking around and all too!!!! then I get a little bit of an adrenaline feeling in my gut from anxiety... Think that would raise it? No! I check again and it's 48!!! Wtf?

I don't know, it just seems low... Probably nothing... Though my chest felt weird right as I stood outa bed and after. You could almost say it was pain... Though more just like tense back muscles.

Also my blood pressure might be On the low side but I'm pretty shure that's normal anyway for such low bpm, and I've always had it. (I black out a bit when I stand sometimes)

I'm 15, 140lbs and excersize moderately.

So given the conditions is this anything to worry about? It's not really my resting heart rate because I was slightly active. I can only imagine what it was when I woke up or when I was sleeping :0

It would be a good idea to see your Dr and tell him/her what's going on. They may order some tests to see if you're anemic or have thyroid problems.They may check you for mitral valve prolapse too.  It's hard to say why your heart rate is low. Only your Dr and possible testing will tell what's going on.

I have been extremely athletic for all my life. Though this past year I have been doing alot less... How fast before your heart becomes less efficient?

I took it for 30 seconds times 2.

And no the rhythm seems off. The consistency of the strength of the beats is different. It will be very strong for a minute, I can feel the blood powering through my fingers. Another minute it will be very weak, some beats undetectable and the blood can barely get past my fingers.

I'm not shure if it skips beats or not...

it's a little less than 60 now, I think I'm okay. Back and chest still hurt though....

How do I feel? Definately not 100%...
Not too bad though...

Anyway thanks for advice!

The accepted definition of "bradycardia" is a heartbeat less than 50.  Your heart rate will be lower in the morning lying down, but when you get up, at least your blood pressure should raise a little bit to compensate for blood rushing into the lower half of your body.  It's not that unusual for people in really good shape to have heart rates that would be considered "bradycardia".  The separation point would be does it make you feel different, weird, odd, basically out of the ordinary.  If it does, you should check with your doctor.  I'm curious, how long did you take your pulse to arrive at 46?  Take it for at least a full minute and when you take it try to notice if it has a regular rhythm.
