I have Fibromyalgia and Chronic Fatigue Syndrome and do suffer with pain and unrelenting fatigue, but this question is related to my heart and exercise. I was diagnosed with an ectopic atrial rhythm last year by a cardiologist, although my primary doctor first called it an ectopic atrial tachycardia. I do have a high resting heart rate - anywhere between 100-115 beats.
This is the problem I've experienced in the past. Before I got sick with Fibro, I was a gym rat and exercised a lot, both cardio and weight training. Since then, my body has just responded poorly to exercise. However, that hasn't stopped me from trying every once in awhile. This is what happens when I do any aerobic exercise: about 20-25 minutes into workout (say with a DVD), I will be working hard, perspiring, breathing hard, as any typical person would respond. But what happens after this 20-25 minute period and I'm about 3/4 done with the routine, I will be overcome with extreme fatigue so heavy that I must lie down immediately and I fall asleep.
This happened most recently about a month ago (the last time I tried to exercise) and it was about 9 p.m., working out to a 30 min. 'walk and kick' DVD and this acute severe fatigue came out of nowhere and my eyes starting closing and I had to slow down and stop and then I laid down and immediately fell asleep.
Does anyone else have this problem or have any ideas as to why this might be happening to me? Even having to walk either a long distance or uphill that increases my HR will result in the same symtoms.
I can't help with the experience, but do ask if you have ever been able to check you heart rate when in the extreme fatigue condition, following exercise? How about your HR before the fatigue cuts in?
You rest heart rate is high enough that I think it should be treated. I'm not sure what can be taken given your fibro condition, but I take a beta blocker to lower my rest HR into the 80s. I suffer from AFib. Beta blockers do have some side effects that may be worse for your condition - something your doctor would take into consideration.
