The Tilt Table Test is used to evaluate causes of syncope (fainting) by reproducing symptoms while closely monitoring the patient. During the test, the patient lies on a table that is tilted to 60-80 degrees for up to 45 minutes. Electrodes monitor heart rate and a blood pressure cuff measures pressure. If no symptoms occur, medication may be administered to increase heart rate and tilt continued. Fainting during the test confirms vasovagal or neurocardiogenic syncope caused by abnormal nervous system reflexes lowering blood pressure and heart rate. The test aims to safely reproduce symptoms to identify causes of fainting.

2. The Tilt Table Test is used to determine a cause of syncope (fainting or loss of consciousness). it is related to an abnormal nervous system reflex causing the heart to slow and the blood vessels to dilate (open up) lowering the blood pressure.

3. When this happens there is a reduced amount of blood to the brain causing one to faint. This type of syncope is called vasovagal, neurocardiogenic or abnormal vasoregulatory syncope it is considered benign -not dangerous , except for the injuries that can happen when one faints unexpec or

5. The Tilt Table Test is performed to reproduce (bring on) symptoms of syncope while the person is being closely monitored. A Tilt Table Test is performed to evaluate one of the causes of syncope (fainting). Vasovagal or neurocardiogenic syncope is when the heart rate slows and the blood pressure decreases because the blood vessels dilate (open) as a result of an abnormal reflex of the nervous system.

7. Preparation for the Tilt Table Test Generally, there is no eating or drinking 4-6 hours prior to the test to limit symptoms of nausea/vomiting physician should see whether patient need to discontinue any of routine medications prior to the test

8. - make the Patient lie down on a special examining table withsafety belts and a foot- rest. - An intravenous line (IV) is inserted into one of patient arms and a blood pressure cuff is attached to other arm to monitor blood pressure during the test. - attached with electrodes to an electrocardiograph ( ECG ) recorder to monitor heart rate.

9. - For safety, patient are belted onto the tilt table. - It is then tilted upright to a 60-80 degree vertical angle for approximately 45 minutes. - Patient are instructed to limit the movement of legs and not to shift weight during the test. Patient should asked to describe any symptoms he/she may be experiencing during the test.

10. even after 45 minutes if patient will not experienced syncope, a medication, usually Isoproterenol/Isupre l that is similar to adrenaline that the body naturally releases, is administered and again patient should be tilted for up to another 45 minutes while heart rate and blood pressure continue to be monitored. If the patient faint during the test, the table will be returned to a flat (horizontal) position and patient should be continued to be monitored closely till recover. Recovery is usually immediate.

11. Typical symptoms of vasovagal or neurocardiogenic syncope includes: Nausea Sweatiness Pallor Lightheaededness Sensation of palpitations Near-fainting Fainting Symptoms frequently happen when standing for long periods or changing positions from lying down to standing.

12. Risks The Tilt Table Test is generally a safe test. Patient are closely monitored and belted safely onto the table. patient may faint during the test. Most people recover once the table is lowered to a horizontal (flat) position. In rare cases a medication has to be administered to help increase the heart rate and blood pressure.

13. Conclusion for the Tilt Table Test If the patient faint during the test, it is considered "positive" for vasovagal or neurocardiogenic syncope. If do not experience fainting during the test it is considered "negative" And should do other tests may need to undergo to determine the cause of your fainting
