Dizziness when standing
Discussion
Recently I have been training a lot. I monitor my resting heart rate and HRV daily. After my last event (half ironman) I rested for a week and then got back on it. I have noticed a sharpish drop in my RHR and a few times when getting up out of a chair I feel a bit dizzy.
I have swapped sensors now and do the measurement sitting down rather than standing but my average RHR has dropped from 67 to 54 in a few weeks. This is taken after having a piss so not completely at rest.
BP is ok at 121/72.
I am a big person as well 6'5'' if that makes any difference. I have had some performance blood markers tested and the results i have so far (Iron/Ferritin) are fine.
Is this just because the fitness ahs lowered my RHR or should it be checked out?

I'm the same. Resting heart rate in the high 40's and if I'm not well rested after exercise I find myself holding on to stuff to stop myself falling down if I stand up too quickly. It's worse if I've just been out exercising in the heat or if I come in and have a hot bath straight away.
I've never been fitter and my blood pressure and cholesterol are bang on. I guess it's just a byproduct of the low resting heart rate.

How old are you? Any medical history? Any family history (did your Dad have heart problems etc)? Ever had an ECG?
36, fit as a fiddle (well a little over weight now but have lost a chunk and losing more). No medical history of anything. I had an ECG done about 4 years ago when my blood pressure was a little high (caused by too much booze and being overweight) and that showed nothing. No heart problems in the family at all.944fan said:

Can I suggest am ECG that lasts 12 seconds isnt going to show a lot ,id ask for an echocardiogram if I were you or at least plant that seed in in your GPs mind. doesnt hurt just lie there while they run an ultrasound looking piece of kit around your heart good luck Definitely get it checked.
Odds are, it is fitness, think they call it athletic bradycardia or something, especially in combination with you being a tall guy, postural hypotension and all, but you CANNOT take the risk of assuming it's that and everything's gravy, it needs to be sussed out properly.
Once issued with a clean bill of health you can then bask in the smugness of being so fit that your heart is strong enough it doesn't even need to beat once a second to do the job properly… well, mostly properly. In the meantime remember to move slowly when standing up cos even if it is just athletic thingywhatsit it won't help a blind bit if you black out and brain yourself on something on the way down!

Actually, a resting ECG can tell you quite a lot. Given his symptoms, I doubt an echocardiogram is really necessary, unless the physical examination throws up a likely structural problem.meddyg said:
