Hi Guys, OK normally my BP is healthy when it's taken by a medic. When younger I even had a low BP at one measurement. I bought one of those wrist BP machines and took my BP after I had been standing up hanging washing up on a clothes airer for about 10 minutes. It was 156 over 85 which my research tells me is classed as a high BP. So I retook it after I had been seated for a while and it was 99/71 (a great one). Is this too large an increase for very little effort, is deconditioning enough to cause this or is it a CFS type symptom? I do have tendency to neurally mediated syncope, which comes on from standing too long, but I thought that was associated with low BP. I previously had the tilt table test done, which is where the finding was from. I started a full faint when the table was upright after I think it was 18 minutes. But their finding was not wholly conclusive, only that I apparently didn't have PoTs. I have also read that there can be false negatives on TT testing. It may be that this rise in BP is fine, I just have no idea and wondered if anyone else knows.
