I was diagnosed with ME/CFS in 2008, now aged 72. During this year I have had a couple of spells of 'funny turns' and feeling unwell and with some different symptoms alongside feeling very fatigued. I just assumed that I had had an ME relapse, due first to a virus in Jan/Feb, and then pushing myself too hard in late May. I also wondered if it was due to low BP, so persuaded a GP to send me for an ECG (EKG in the US?).
It seems it was likely not low BP after all, as my BP was normal, and maybe my machine is wrong, despite sending it back to the manufacturer who said it was 'normal' .
However, the ECG showed that it was abnormal and I have a heart 'block' which is not a blockage, but a problem with the electrics system in the heart, or otherwise known as a conductor disorder. So my left ventricle's nervous system I think, doesn't fire at the right time in conjunction with the other side, or something like that, or it could be a bit slow. I am seeing the GP on Tuesday to discuss, and maybe she will send me for an echocardiogram, to see if anything in particular in the heart is affected.
I do know that some people don't have symptoms, but I worry that I DO have symptoms, or sometimes at least, especially fatigue, and I wonder if my so-called ME has been this issue all along, though i do know that this particular heart block tends to affect older people, so it's possible that the 2 are not connected.
