I have a question for you about the heart. I am involved in a lung health class at our local hospital due to a diagnosis of asthma and chronic bronchitis and we are not only learning to breathe but also involved in exercise that is moderated by Respiratory Therapists. I have been diagnosed RRMS and am currently on Elavil 20mg/day, Tegretol 300mg/tid, Citalopram 20mg/day, Symbicort bid, Spireva once a day and Singulair. I recently have developed a problem with blood tests in that I faint while blood is being taken and I have to lie down to have it taken. This has developed over the last 6 months. I went to my exercise program yesterday and wasn't feeling too well even before I left the house...pain in my legs, exceptionally tired, just not feeling up to too much but went anyway. We had to do a 12 minute walk first but before we start they check our resting BP, Heart Rate and O2 level. So resting my heart rate was 94 and it is always between 90 and 95. So I started walking and did so for 6 minutes and then they checked my heart rate and O2 level with their little machines that they use with that doodad that they put on your finger. So when she checked the heart rate it was at 61 after walking as fast as I could for 6 minutes! So she got a different machine and tested it again and again it was 61! So the head RT checked it with my pulse on my wrist and AGAIN it was 61!!! So they told me to keep walking which I did for an additional six minutes and then they tested my heart rate again...once with the 1st machine, once with the second machine and then with my pulse on my wrist and it JUMPED to 112!!! They were rather concerned about this but didn't really elaborate on it and I am wondering if I should see my doctor about this? I was also unable to do ANY exercises with my legs today...I tried the bike and only could do about 45 seconds and my legs just gave out completely! Continued......
