Head-up tilt table testing is a standard tool for evaluating children with dizziness and/or episodes of syncope (passing out). 

When a child undergoes a tilt table test, he/she lies on a table for 20 minutes, after which the table is placed at an incline.  Your child's heart rate and blood pressure are monitored during the study.  The test may precipitate symptoms of dizziness, nausea, or syncope, which is helpful in assessing some children with these symptoms.  In some cases, an IV may be placed and a medicine given to bring out these symptoms.

The duration of the test may range from 30 min-1 hour, and the results are discussed immediately following the study.
