A tilt table test is used to diagnose if postural orthostatic tachycardia syndrome (POTS) or neurally mediated hypotension (NMH) is the cause of your dysautonomia, light-headedness, or syncope. Vital signs, especially heart rate and blood pressure are monitored as the table slowly raises the patient from lying to nearly standing position. The patient is strapped to the table in case the patient faints in the upright position. Other conditions that can be diagnosed with a tilt table test is cardiac arrhythmia.[1]

Recommended test for ME/CFS[edit | edit source]

The Institute of Medicine Report recommends a tilt table test for diagnosing orthostatic intolerance in ME/CFS.[2]

Beyond Myalgic Encephalomylitis/Chronic Fatigue Syndrome: Redefining an Illness (2015) pgs. 111-119 covers Tilt Table Test: "Assessment of Orthostatic Intolerance and Autonomic Dysfunction in ME/CFS"[3]

Risks[edit | edit source]

A tilt table test is generally safe, and complications are rare. But, as with any medical procedure, it does carry some risk.

Potential complications include:

  • Nausea and vomiting after fainting
  • Weakness that can last several hours
  • Prolonged low blood pressure (hypotension) after the test

These complications usually go away when the table is returned to a horizontal position.[4]

tilt table test - A diagnostic test to determine orthostatic intolerance or other forms of dysautonomia. The patient is strapped to a table and the table is tilted while the patient is monitored.

postural orthostatic tachycardia syndrome (POTS) - A form of orthostatic intolerance where the cardinal symptom is excessive tachycardia due to changing position (e.g. from lying down to sitting up).

lightheadedness - the condition of being dizzy or on the verge of fainting

ME/CFS - An acronym that combines myalgic encephalomyelitis with chronic fatigue syndrome. Sometimes they are combined because people have trouble distinguishing one from the other. Sometimes they are combined because people see them as synonyms of each other.

chronic fatigue syndrome (CFS) - A fatigue-based illness. The term CFS was invented invented by the U.S. Centers for Disease Control as an replacement for myalgic encephalomyelitis (ME). Some view CFS as a neurological disease, others use the term for any unexplained long-term fatigue. Sometimes used as a the term as a synonym of myalgic encephalomyelitis, despite the different diagnostic criteria.

tachycardia - An unusually rapid heart beat. Can be caused by exercise or illness. A symptom of postural orthostatic tachycardia syndrome (POTS). (Learn more: www.heart.org)

myalgic encephalomyelitis (ME) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.
