Physician Benefits

VitalScan ANS+ is a valuable tool in diagnosing hidden illnesses. Medical practitioners can quickly and easily test patients and receive immediate comprehensive interpretive reports.

VitalScan ANS+ has 39 standardized tests and can customize testing protocols.

Why Test ANS?

  • "According to Published Studies "Cardiovascular autonomic neuropathy occurs in about 17% of patients with type 1 diabetes and 22% of those with type 2"
  • "Of patients with symptomatic autonomic dysfunction, 25% to 50% die within 1 to 5 years of diagnosis."
  • "A patient's history and physical examination are ineffective for early detection of CAN, and therefore noninvasive tests that have demonstrated efficacy are required".
  • "Screening for Autonomic Neuropathy should be instituted at Diagnosis of Type 2 Diabetes and 5 years after the diagnosis of type 1 Diabetes - 2005 ADA Standard of Diabetes Care"
  • "Although it can cause severe cardiovascular problems and sudden death, surveys show that only 2% of people with diabetes are tested for cardiovascular autonomic neuropathy (CAN)".

What is Autonomic Nervous System (ANS)

The Autonomic nervous system (ANS) regulates physiological processes, such as blood pressure, heart rate, body temperature, digestion, metabolism, fluid, electrolyte balance, sweating, urination, defecation, and sexual response. Regulation occurs without conscious control, i.e., autonomously. The ANS has two major divisions: the sympathetic and parasympathetic systems. Many organs are controlled primarily by the sympathetic or parasympathetic system, although they may receive input from both; occasionally, functions are reciprocal (e.g., sympathetic intake increases heart rate; parasympathetic decreases it).

The sympathetic nervous system is catabolic and activates fight-or-flight responses. Thus, sympathetic output increases heart rate and contractility, bronchodilation, hepatic glycogenolysis and glucose release, BMR (basal metabolism rate), and muscular strength; it also causes sweaty palms. In addition, more minor immediately-life-preserving functions (e.g., digestion, renal filtration) are decreased.

The parasympathetic nervous system is anabolic; it conserves and restores. As a result, gastrointestinal secretions and motility (including evacuation) are stimulated, slowed heart rate, and blood pressure decreases.

Disorders of the ANS can affect any system of the body; they can originate in the peripheral or central nervous system and may be primary or secondary to other disorders. Symptoms suggesting autonomic dysfunction include orthostatic hypotension, heat intolerance, nausea, constipation, urinary retention or incontinence, nocturia, impotence, and dry mucous membranes. If a patient has symptoms suggesting autonomic dysfunction, cardiovagal, adrenergic, and sudomotor tests are usually done to help determine the severity and distribution of the dysfunction.

Autonomic Regulation is the body's ability to maintain homeostasis (stability and balance) during internal and external stimuli. Autonomic Regulation is always functioning, and we are often unaware of the crucial tasks. When the nerves that control Autonomic Regulation are damaged, Autonomic Dysfunction can develop. Autonomic Dysfunction can be temporary or chronic. Diabetes and Parkinson's disease are two examples of chronic conditions that can lead to Autonomic Dysfunction. VitalScan ANS+ tests Autonomic Regulation through a combination of Heart Rate Variability (HRV) Assessment and Cardiac Autonomic Reflex Tests (CARTs).

Cardiovagal innervation testing evaluates heart rate response to deep breathing and the Valsalva maneuver via electrocardiogram rhythm strip. If the ANS is intact, heart rate varies with these maneuvers; the Valsalva ratio of longest to shortest HR should be 1.4 or greater.

Vasomotor adrenergic innervation testing evaluates the response of beat-to-beat blood pressure to the head-up tilt and Valsalva maneuver. The head-up tilt shifts blood to dependent parts, causing reflex responses. The Valsalva maneuver increases intrathoracic pressure and reduces venous return, causing blood pressure changes and reflex vasoconstriction. In both tests, the pattern of responses is an index of adrenergic function.

Cardiac Autonomic Testing Benefits

Cardiac Autonomic Testing measures neuro-cardiac function, reflecting heart-brain interactions and autonomic nervous system dynamics. The autonomic nervous system is involved in the function of virtually every organ system, and clinical manifestations of autonomic dysfunction are involved in just about every disease. As a result, ANS analysis is used as a screening and monitoring tool in many disease processes.

Autonomic Function Assessment has acquired exceptional popularity over the last few years. Nowadays, the mainstream medical associations worldwide accept ANS studies as one of the best predictors of specific and non-specific health risks. In addition, scientific and clinical studies have established their usefulness in almost all branches of medicine.

VitalScan ANS+ delivers laboratory analyses to the physician's office, enabling professionals to assess patient health conveniently and reliably.
Applications include:

  • Verifying the effectiveness of treatment and intervention
  • Monitoring overall patient health
  • Screening the general population
  • Identifying various health issues such as heart palpitations, pain management, sleep apnea, anxiety, stress, psychological disorders, asthma, and neurological conditions
  • Examining for Cardiac Autonomic Neuropathy (CAN) and Diabetes Autonomic Neuropathy (DAN)
  • Measuring the Sympathetic Nervous System's predominance in cases such as Metabolic Syndrome, Hypertension or Heart Failure
  • Screening for unfavorable in the absence of clinically apparent health situations

How Is the Test Performed?

The test involves four phases, each designed to determine a particular aspect of the patient's Autonomic Nervous System function.

  • Resting Phase:
    Heart Rate Variability (HRV) analysis combined with beat-to-beat blood pressure is measured to obtain a baseline of how the autonomic system is functioning during the resting phase.
  • Deep (Metronomic) Breathing Test:
    Heart Rate Variability combined with beat-to-beat blood pressure is measured and monitored during Deep Breathing. Additional comparisons are made to determine the changes during Deep Breathing from the baseline and the baroreflex response.
  • Valsalva Test:
    Heart Rate Variability combined with beat-to-beat blood pressure is measured during Valsalva Maneuver. Additional monitoring and comparisons are obtained to determine the change from the baseline compared to the Valsalva maneuver.
  • Standing or Tilt Test:
    Heart Rate Variability coupled with beat-to-beat blood pressure is monitored and measured during Standing/Tilt, and changes are compared with the baseline.

The data obtained from the ANS test evaluates the Parasympathetic (rest and digest) and the Sympathetic (fight, flight response) system, and entire ANS system balance.

Obtaining objective data on the ANS parasympathetic and sympathetic components can pinpoint health risks such as sudden death, silent heart attacks, syncope, hypertension, and other hidden diseases. Beat-to-beat blood pressure under various conditions can test adrenergic functions for conditions like orthostatic hypotension (OH). OH is widely known to be a consequence of chronic diabetes frequently found amongst the elderly population. Since many OH symptoms can be difficult to trace - impaired concentration and fatigue. ANS testing can fill this void and bring these problems to light sooner.
