What is VSAT Testing?

What is VSAT?

VSAT, or Vital System Assessment Test, refers to a series of tests encompassed by the VSAT. These tests include the sudomotor function, the heart rate variability and the pulse wave velocity. The VSAT testing equipment used is FDA-compliant, comfortable, and conveniently located in our office.

It is extremely common for medications, therapies, and treatments to be changed once these tests have been performed. Suggestions are also often made for further testing. These additional tests can save lives by taking an individual off a medication that is causing issues, or not working. These tests can also improve the quality of life, health, longevity or symptoms by recommending new supplements, medications or therapies.

The VSAT tests are typically restful, simple and pleasant. It is not uncommon for the patient to fall asleep while the tests are being conducted. The length of the tests are dependent on the medical history of the patient but generally require fifteen to thirty minutes. Most patients who have the VSAT tests, follow up with additional tests. These tests have been classified as preventative. This means they are usually fully covered by all insurance carriers.

VSAT testing is recommended for many individuals and the benefits are excellent. These tests help individuals ensure they are taking the correct medications for any medical conditions they have. They accurately provide the information necessary for any additional supplements or medications to be recommended for the safety and health of the patient.

Have you ever felt older than you are? 

Often, this can be due to unhealthy decisions we have made over the years. Everyone wants to look and feel younger than they are, right?  Fortunately, if appropriate changes are made early enough, you can look and feel younger! How do you know your functional age? 

VSAT stands for Vital Systems Assessment Test. It is a combination of three tests: Heart Rate Variability, Pulse Wave Velocity, and Sudomotor Function. 

This amazing machine is used to screen patients for cardiovascular disease. A VSAT screening consists of three separate tests.

The first test, the heart rate variability test, measures wave intervals in your heart’s rhythm. It effectively measures parasympathetic and sympathetic balance, letting your physician know if you have atherosclerosis or other cardiovascular issues.

With the second test, the pulse wave velocity test, your arteries are evaluated for elasticity. This test is a reliable predictor of stroke and myocardial infarction, among other heart problems.

The sudomotor function test, the third test, checks your nervous system. It points out neuropathies, or painful nerve abnormalities, which are signs of damage from diabetes.


Combined, these tests have successfully shown cardiovascular and nervous system issues, long before other standardized tests.

Saves Lives and Quality of Life

  • VSAT testing provides vital information about your health before other tests do, allowing you and your doctor to intervene early to prevent further problems.
  • One of the VSAT tests, Heart Rate Variability, is the only test for the risk of sudden cardiac death.
  • One in every 100-150 VSAT tests done will lead to lifesaving intervention.

Covered by Medicare and Most Insurances

  • VSAT testing is fully covered by Medicare and private pay insurance, for patient's who qualify for the test by medical necessity guidelines.
  • VSAT tests provide your doctor's office with a detailed screening questionnaire to determine your eligibility
  • You may be eligible for re-testing every year or more frequently if there are medication or other significant changes.

Is VSAT testing Right for You?
Only your doctor can determine whether VSAT testing is necessary for you. Your doctor bases this decision on a number of factors such as your medical history, symptoms, and risk factors. If your doctor does advise you to be tested, it is because they feel that doing the test could potentially save your life, help preserve your quality of life and because it would provide valuable information with which to monitor and evaluate relevant medical conditions you may have. It will be used as a "health tracking" evaluation in your course of care.
