Comprehensive Autonomic Nervous System Testing

Autonomic Nervous System (ANS) testing correlates signs and symptoms of possible autonomic dysfunction with objective measurement in a fashion that is clinically useful.

The Intellewave tests for several of the most common risk factors in patients through a variety of diagnostic testing solutions such as:

Autonomic Nervous Testing (ANS)

Endothelial Testing

Tilt Table (Syncope)

Cardiometabolic (BMI)

Vascular Testing (ABI)

The Intellewave Difference:

There are many systems that claim the ability to automatically measure the Autonomic Nervous System, measuring the dysfunction of the sympathetic and parasympathetic systems renders a plethora of data to physicians.

However, the Intellewave measures the system in real time over an extended period using ECG electrocardiogram based testing, rather than PPG or plethysmography based testing. Not only has CMS Medicare deemed ECG testing more accurate but also more comprehensive than its PPG counterpart.

The Intellewave system provides maximum flexibility and diversity with its holistic mobile cart management system that allows physicians to provide world class holistic testing of the autonomic nervous system in less than 30 mins. The seamless and intuitive red, yellow, green reports that follow will allow doctors to easily assess where patients lay in comparison to normal standard deviation of a healthy patient Autonomic nervous system.


Beat to Beat blood pressure monitoring:

HRV or Heart Rate Variability testing with Intellewave system enables physicians to detect specific types of autonomic dysfunction that may be linked to a multitude of clinical diagnoses.

Additionally, Intellewave is a tool for overall, general assessment of a patient’s physiology, and as such, provides a comprehensive, in-depth patient evaluation, often missing in standard medical practice.

The wide range of Intellewave’s clinical applications and distinguishes it favorably from all other diagnostic devices based on HRV analysis.

Intellewave objectively and reliably evaluates the state of ANS in “real-time” as well as during Orthostatic test and Valsalva maneuver combined with deep breathing.

Due to its highly sophisticated HRV (Heart Rate Variability) analysis, Intellewave is the only system that enables quantification of 81 ANS states with a corresponding qualitative description for each one.

What’s included in the Intellewave System

ECG and HRV Analyzer Software for display, measurement and
interpretation of test results

PC ECG USB device (Pulse Biomedical Inc) or Bluetooth wireless
acquisition device (Corscience Gmbx)

Automatic blood pressure-measuring device

Laptop computer with integrated Bluetooth and portable printer

Add on Options for Intellewave Platform:

These additional add on components help provide more data to the physician and also help to increase reimbursement for ANS testing. You do not specifically need to add any of these components but they are recommended to maximize patient usage data for the diagnostic report and so that the provider will have the ability to suggest the best treatment regimen for the patient.

QSART (Quantitative Sudomotor Axon Reflex Test)

The QSART measures axon reflex-mediated sudomotor responses quantitatively and evaluates post-ganglionic sudomotor function. Recording is usually carried out from the forearm and three lower extremity skin sites to assess the distribution of post-ganglionic deficits. Sweat imprints are formed by the secretion of active sweat glands into a plastic (silastic) imprint. The test can determine sweat gland density, a histogram of sweat droplet size and sweat volume per area. This is especially useful when diagnosing small nerve fiber neuropathies or other neuropathies in general.

Tilt Table (Syncope Testing)

A tilt table test is utilized to evaluate the cause of unexplained fainting (syncope). If a patient is exhibiting unexplained episodes of lightheadedness, dizziness or fainting, a tilt table test can be used to trigger those corresponding signs and symptoms. The test can help determine if the cause is related to the patient’s heart rate or blood pressure. If the patient shows symptoms while in the upright position on the tilt table, the part of their nervous system that controls blood pressure and heart rate suddenly drops for a short time. Less blood flow to the brain possibly might be the culprit for the unexpected fainting. This combined with other testing of sympathetic and parasympathetic systems will provide the physician with more holistic data to make an informed decision as to what might be going on internally.

ABPM (Ambulatory Blood Pressure Monitoring)

Ambulatory monitoring can rule out white coat hypertension, so that patients are not given unnecessary prescriptions for BP-lowering drugs. It can also detect masked hypertension, so that patients receive the medications needed for high blood pressure. The incidence of stroke, heart disease, and organ damage due to hypertension can be reduced among those patients. Ambulatory monitoring may also be useful in evaluating a patient’s response to long-acting anti-hypertensive medications. Ambulatory BP monitoring can also help to predict the likelihood of cardiovascular (blood vessels in the heart) and cerebrovascular (blood vessels in the brain) disease linked to hypertension and organ damage.

Holter Monitoring:

Holter or event monitoring is a tracing technique used for patients whose heart conditions cannot be properly diagnosed through an EKG. These medical devices record the electrical activity of the heart and are often used to diagnose arrhythmia. Since an EKG only lasts for a few minutes, it may not detect any heart abnormalities if they are not present at that time. The Holter monitor is worn for 24 hours and records the heart’s activity throughout that time. This helps to detect arrhythmia that may only occur at certain times, such as after physical exertion. There is no risk involved in using a Holter monitor. Although some conditions still may not be diagnosed with this device, it is often helpful in identifying the cause of heart rhythm problems.

ABI – (Doppler Based Ankle Brachial Index) Vascular Testing

The ankle-brachial index test is a quick, noninvasive way to check your risk of peripheral artery disease (PAD). Peripheral artery disease is a condition in which the arteries in your legs or arms are narrowed or blocked.

People with peripheral artery disease are at an increased risk of heart attack, stroke, poor circulation and leg pain.

The ankle-brachial index test compares your blood pressure measured at your ankle with your blood pressure measured at your arm. A low ankle-brachial index number can indicate narrowing or blockage of the arteries in your legs, increasing your risk of circulatory problems, and possibly causing heart disease or stroke.

The ankle-brachial index test is sometimes recommended as part of a series of three tests, including the carotid ultrasound and abdominal ultrasound, to check for blocked or diseased arteries.
