As part of the ongoing investigations into my blackouts, I went to Cheltenham today for a tilt table test. This involves being strapped into a table and connected to an ECG machine, heart monitor and blood pressure cuff. They then tilt you at 70 degrees and monitor your levels. After about 20 minutes (which feels like an hour when you can't move, talk or walk) they induce an episode by giving you GTN (glyceryl trinitrate) which makes your heartrate increase about 3 fold so you feel like your head is going to explode. I didn't have a full blackout but I think they got the readings they needed. Before giving me the GTN the doctor said "it may give you a bit of a headache". Suffice to say I was ill from the moment I left the hospital and have had a serious episode all afternoon flipping in and out of consciousness. It was a good job Tree was with me all day to manage the episode as I was originally going to take the train to Cheltenham!!
I see now what the consultant meant when he said "No one likes a tilt test".
