Autonomic Nervous System Testing

At The Heartbeat Clinic, we provide detailed Autonomic Nervous System (ANS) testing to diagnose complications associated with the autonomic nervous system. You will receive an accurate diagnosis from our highly skilled physicians, along with comprehensive reports from our advanced technological equipment, facilitating proper management and treatment of your autonomic function and any related conditions.

What is Autonomic Nervous System Testing?

Autonomic Nervous System Testing comprises a set of diagnostic tests that are non-invasive or minimally invasive techniques aimed at examining the performance of the autonomic nervous system. This system regulates vital physiological processes like heart rate, blood pressure, digestion, and sweating. These tests assist in the diagnosis of disorders affecting the sympathetic and parasympathetic branches of the nervous system.

Purpose for Autonomic Nervous System Testing

Autonomic Nervous System Testing is performed to:

  • Diagnose Autonomic Disorders: Detect conditions such as orthostatic hypotension and autonomic neuropathy, which manifest through changes in blood pressure, pulse rate, and other autonomic dysfunctions.

  • Evaluate Symptoms: Investigate symptoms related to autonomic dysfunction like dizziness, fainting, tachycardia, excessive sweating (hyperhidrosis), or gastrointestinal disturbances.

  • Monitor Disease Progression: Assess how conditions such as diabetes, Parkinson’s disease, or multiple system atrophy affect autonomic function over time.

  • Guide Treatment Plans: Provide crucial data for designing individualized patient care plans and assessing the efficacy of implemented treatments.

Methods of Autonomic Nervous System Testing

Heart Rate Variability (HRV) Testing

Measures the variations in time intervals between successive heartbeats, reflecting the balance between sympathetic and parasympathetic nervous activity.

Tilt Table Test

Evaluates how your blood pressure and heart rate respond to changes in position, helping to identify conditions like orthostatic hypotension.

Quantitative Sudomotor Axon Reflex Test (QSART)

Assesses the function of the sweat glands and the nerves that supply them—helpful in detecting small fiber neuropathy.

What to Expect During Autonomic Nervous System Testing?

Preparation

Depending on the tests to be conducted, your healthcare provider may have specific instructions, such as avoiding certain medications or foods before the test.

 

Procedure

The process varies based on the specific tests being performed. 

  • During a Tilt Table Test, you will be secured on a tilting table to observe your body’s reactions as the table moves to different angles. 
  • For Heart Rate Variability (HRV) Testing, electrodes are placed on your chest to measure heart rate variability while you rest. 
  • In Quantitative Sudomotor Axon Reflex Testing (QSART), small electrodes are attached to your skin to stimulate sweat glands and measure their response.

Monitoring

These tests are non-invasive or minimally invasive and typically take about 30 minutes to an hour. Our medical team will ensure you are comfortable and safe throughout the procedures.

After the test

Your doctor will discuss the results with you and provide further management recommendations if needed.

Risks

Autonomic Nervous System Testing is generally safe with minimal risks. Some patients may experience mild discomfort or dizziness during certain tests; however, these side effects are temporary and usually resolve quickly.

Results
