Hi...I had drop attack which many people confuse for passing out....and if it is a drop attack then a tilt table test may not show anything.....
It really depends on what other symptoms you have....I did not have a tilt table test...and y drop attacks stopped with my surgery.
Having the right Dr is key and it is frustrating as it is difficult to know whom to listen to....all we can do is research the condition, and ALL related conditions and the Drs we go to see and choose a true Chiari specialist....they will know if a tilt table is required....
It is a related condition so well worth it to have it ruled out if this Dr feels you possibly have it....with a drop attack there are no advance warnings with issues like hot flashes etc...you are fine one moment and the next you are aware you are mid-fall but no idea why and unable to react or call for help.It also took time for me anyway to be able to communicate and get up and move and I was extremely nauseated after.
If you can, have the testing....one more thing to rule out or in,,,,,
