Dizziness when standing

[944fan]

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?

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.
