Today I had the exertion test in the CFS centre in Amsterdam. We had to be there at 9.15 am, so we had to drive through the morning rush-hour. It took almost thrice the normal time.
First they made an ECG. I also had to do a longfunction test; that went okay, I scored 98%. Then I put on my sportswear and climbed on the exercise bike. I had a mask on to breathe through, a zillion stickers on my body with wires, a clip on one finger and something around another finger; I must have looked like an alien! ;-) The test itself was quite tough. I could say when to stop, but of course I didn't want to quit too soon. I cycled for 20 minutes or so. Afterwards I was dizzy and exhausted.
Although all the results have to be reviewed in the team, the doctor told me his first impression. It looks like the oxygen and carbon levels in my blood are off when I strain myself, which makes me dizzy and tired, and give me a dry throat. If that's the case I should do the same bike test again in the VU hospital, where they can observe the levels in my blood directly when I'm cycling. I can call in 3 weeks for the overall results. At that time we make another appointment to talk things over and see what we can do next.
At the end I got a portable device strapped on for 24 hours. It will measure and record my blood pressure every 30 minutes. It started 11am this morning and stops 11am tomorrow morning. The band around my arm and the small hose are inconvenient and irritating, but it's okay. When I took a nap this afternoon I was so tired it didn't wake me up, so I hope I'll sleep somehow tonight. I can see the measurements too. My blood pressure varies from 150-165 over 110-125 up until now.
