Like Sally said, the tilt table is the most common test. Don't worry about falling off or problems with the test...you are strapped to the table and the tilting is not fast. It's similar to just checking BP & heart rate while laying down, sitting, then standing...just in a more controlled way since you are strapped to the table and have monitors, etc. Pretty easy test.

In some (but NOT all) patients they give a medicine to try to induce the symtpoms. I never needed that because my dysautonomia was so profound and always detected immediately.
