ANS testing is based on heart rate variability (HRV) which monitors the R-R intervals, respiration rate, blood pressure and pulse wave form through different parts of the test. The general concept is for the patient to perform a series of maneuvers while the ANS system monitors the body’s response. The system looks at changes in heart rate, blood pressure and respiration rate to calculate parasympathetic & sympathetic system responses.
The guidelines for testing are clear as there is a certain protocol for acquiring reliable and accurate results. ANS testing can be tolerated by most patients as there are specific maneuvers required to be performed throughout the test. The test includes 4 sections. These sections include:
The technologies for testing the Autonomic Nervous System have evolved tremendously since they emerged more than 10 years ago. The systems are faster, more accurate, easier to operate & integrate multiple testing modalities into one device. The ANS Sudomotor combined system is the most advanced technology available for Autonomic Nervous System (ANS) testing. The ANS Sudomotor combined device is a revolutionary system that combines multiple parameters into one single system.
