During the test, you will lie down on a table and the table will elevate to a 60- to 90-degree angle so the head is above the body. A nurse will monitor your heart rate and blood pressure as it responds to gravity for five to 45 minutes, depending on the reason for the test. In some cases, you will be given a medication called nitroglycerin which dilates the blood vessels.

If you do feel any symptoms such as dizziness, nausea, sweating, lightheadedness or irregular heartbeat, please let your healthcare provider know right away.

Patients who are experiencing unexplained, recurring syncope episodes (with or without the loss of consciousness) are candidates for a tilt-table test.

Although a tilt-table test is typically very safe, potential complications can occur. Complications include:

• Extended period of low blood pressure
• Extended period of pause between heartbeats
• Fainting
• Dizziness or headache
• Palpitations

Symptoms are relieved when the table returns to a flat position. It is important to communicate with your doctor or nurse during the procedure if you are experiencing any new or abnormal symptoms.

Most patients can resume their normal activities right after a tilt-table test. Stay in regular contact with your doctor if you are continuing to have symptoms during and after the treatment.
