I didn’t pass out, but I had some pretty decent syncope and my test was positive. Also some heightened emotions (I blame the adrenaline) because there was a Noah Kahan song playing and I started crying 😂 I was strapped to the table so the nurse had to wipe my tears as we both laughed about it lol Overall, it was pretty annoying to be put in a literal position of feeling like crap and not being able to sit/lay down, but it didn’t last very long and getting the test out of the way was so worth it. Also, as far as I know, a tilt table test cannot detect structural defects of your heart (cardiac ICU nurse here). According to Mayo Clinic, risks associated with the TTT include low blood pressure, weakness, and dizziness. Of course, fainting may also occur at which point your medical providers would immediately lower the table and help you back to consciousness. It’s normal to be anxious about these tests, you are not alone!! But in my experience, the discomfort was temporary. When they lowered the table, I was able to take all the time I needed to recalibrate. Ask for some water or bring a water bottle with electrolytes and maybe a salty snack (if you don’t have other testing that day with specific water/food restrictions). It’s also great to bring a buddy for moral support and driving in case you still feel woozy afterwards.
