What is the Tilt Test (Tilt-Table Test)?
The Tilt test, also known as tilt-table test, is a test developed to identify a type of syncope (fainting) mediated by the central nervous system. This type of syncope can affect people of all ages, but is more common in young adults and adolescents. The test has been widely used by neurologists to distinguish fainting from episodes caused by seizures.
How is the Tilt Test performed?
The test is performed on an outpatient basis, meaning the patient does not need to be hospitalized. To undergo the test, the patient must be fasting for at least four hours and bring previous tests such as Holter, echocardiogram and exercise stress test, if available.
During the test, the patient is placed on a special tilting table that allows assessment at different angles (0, 80 and -30 degrees). The table has safety devices that keep the patient secured, preventing falls in the event of fainting. During the test, the patient is monitored electrocardiographically and blood pressure is measured every two minutes.
When indicated by the medical team, a nitrate may be administered to increase the sensitivity of the Tilt Test. During this stage, heart rhythm, blood pressure and symptoms are monitored to assess the body’s response to tilting. At the end, the patient receives instructions from the team before being discharged. The test recordings are analyzed and compiled in a report to help the referring physician assess the patient and guide treatment.
