Cardiac problems

[Loub37]

Hello again, I'm still battling with Levothyroxine & what a battle it's turning out to be! I was just wondering if anyone could tell me why my pulse is slow (56-60) & then when I put the body under a bit of physical stress, my heart rate goes up to 80+ beats per minute. I feel completely exhausted & can't do anything for hours.I also feel like I'm going to blackout. I'm on 75 mcg & have been on that dose for about 5 wks now.

Thanks in advance.

I have a normal pulse at 60 but when I lie down and think about it, it usually jumps to 80-85. It seems to be psychological. As long as your pulse is not under 50 or over 100, it's normal.

resting pulse of course. A pulse under physical stress means nothing. Some athletes have a resting heart rate at 40 and it can jump to 200 if needed - Andy Murray for instance.

Thanks for your reply Natalie. It's just that I feel completely exhausted after & can't do anything for hours.

Mine can go from really low to pretty high in quite a short time but it goes down quickly as well. If you are worried speak t your doctor about it. It might be worth taking readings at home and taking a list of times and dates - my surgery had one you can print off and fill in.

My pulse and BP go off the scale when I have them taken at the surgery so I always do my own and take my record with me.

It helps to relax for a few minutes before you take it, I read a book, then wait for five minutes between each reading, again I read and I do three readings at five minute intervals. never talk while you are having your BP measured.

I think the thing here is that you say you don't feel good after it has been high, get checked out and then you will be able to relax about it.

Thanks for your reply Fruit and nutcase. I will bear that in mind. It doesn't feel very normal that's all & I am starting to feel tired all the time. Maybe I need more thyroxine again.

I would definitely get thoroughly checked out, I'm sure will feel better once you've had that done.

Yes I think I will. Thanks again for your help.
