Maybe “failed” wasn’t the best term to use. Neither myself nor my cardiologist expected the results that occurred with the tilt table test. From my description, he thought that my dizzy spells were from vertigo, so we weren’t expecting my BP to plummet like it did. I made through the test, barely. After the nurse brought the table back into a horizontal position and put me on oxygen, she began fluid bolus which is a rapid infusion to correct hypotensive shock.
