Autonomic Function Testing 



Neurologist Dr. Laurence Kinsella provides very specialized testing at SSM Health St. Clare Hospital to pinpoint the causes of autonomic nervous system problems. The service is the only one of its kind in the St. Louis region.

Autonomic nervous system testing focuses on the nerve connections between the brain, heart and other organs. Non-invasive testing checks for imbalances that control autonomic processes that include heart rate, blood pressure, gastrointestinal function and sweating.

Autonomic nervous system testing may be used to evaluate and treat:

  • Recurrent fainting and syncopy
  • Dysautonomia
  • POTS (Postural Orthostatic Tachycardia Syndrome)
  • Autonomic failure
  • Neurogenic orthostatic hypotension
  • Orthostatic intolerance
  • Small fiber nerve function
  • Sweat disorders such as anhidrosis and hyperhidrosis

Tilt Table Testing
This test helps to determine how blood pressure and heart rate change in response to body position. The table rotates the body at various upright angles and accentuates the force of gravity and lessens muscle tone. It can show, for example, if a patient is disposed to low blood pressure or to fainting during these physiologic events.
