Artist rendering of nerves.The autonomic nervous system helps us to internalize and navigate the interactions between our external environment and our internal balance. The Center for Healing Neurology in Seattle offers a full autonomic laboratory including quantitative sweat measurement system, and beat-to-beat blood pressure acquisition for testing of cardiovagal (parasympathetic) function, adrenergic (sympathetic) function, and sudomotor axon reflex function. These autonomic tests are non-invasive, easy to perform, and offer important and useful objective information on the health of your autonomic nervous system. We diagnose and treat dysautonomias such as POTS, small fiber neuropathy, autoimmune autonomic neuropathies, alpha-synucleinopathies, ganglionopathies, and more. Our testing includes:

  1. Tilt Table Testing: laying down then stood up on a table to 70’ for 10 minutes with measurements taken the whole time for blood pressure, heart rate & breathing pattern.
  2. Heart Rate Deep Breathing x 8 breaths. 2-3 trials with measurements.
  3. Valsalva x 2-4 trials- this is a pressurized exhalation x 12 seconds with measurements.
  4. QSART test which attaches leads (1 left forearm and 3 left lower leg/foot) with topical application of acetylcholine to measure sweat levels, a reflection of the sympathetic nervous system on the periphery of the body. QSART stands for Quantitative Sudomotor Axon Reflex Test.
  5. Final interpretative report within 2 weeks.
