  • 1. Tilt Table Test (HUT Head Up Tilt) Kiran rai Bsc .CVT(II YEAR)
  • 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
  • 4.  
  • 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.
  • 6.  
  • 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
  • 14.
    • INDICATIONS -, RECURRENT SYNCOPE OR PRESYNCOPE
    • SINGLE SYNCOPE WITH SERIOUS CONSEQUENCES
    • AUTONOMIC FUNCTION TESTS
    • SITUATIONAL SYNCOPE
    • OH
    • POTS
    • CAROTID SINUS HYPERSENSITIVITY.
