How is it done?
When you have your tilt test:

• You lie on a table that slowly tilts you to a 70 degree angle.
  
• Your heart rate and blood pressure are monitored with a non-invasive blood pressure cuff placed on the right arm.
  
• After 15-20 minutes, you are returned to a lying position.

Head - up tilt test
If the first test is positive (a blood pressure drop and similar symptoms as before), you may be given medication in an IV (a small tube in the arm vein) to reduce your symptoms, and the test is repeated as before.If the first test is negative (no blood pressure drop or symptoms), you will be given medication in an IV to increase your heart rate, and the test is repeated as before.
