A tilt table test is a safe test. There are not many risks associated with the test. Some people may experience nausea, dizziness, vomiting, and loss of consciousness during the test. The test is performed under careful monitoring, and if any of the symptoms occur, they can be managed easily. If you suffer from any serious heart problem or excessively low blood pressure, your doctor will not prescribe the tilt table test for you. A serious heart problem will pose a high chance of fainting, and the test may not give any further information to the doctor if you are already suffering from such a problem.
