The head-up tilt table test usually takes one to two hours to complete. However, that may vary depending on the changes observed in your blood pressure and heart rate and the symptoms you experience during the test. Before the test begins, a nurse will help you get ready. The nurse will start an IV (intravenous) line.
The angled position has to be held in one place for the entire test. I was tied in the angled position and then elevated and moved into a wide tube. The test took about 15 minutes of prep time and the test itself took about 45 minutes to complete. My muscles were screaming in pain by the time the test was done. The vibrations from the MRI machine irritated the nerve endings in my arm, which was like running fingernails down a chalk board, only inside my body.
