POTS Testing and Diagnosis in Phoenix, Arizona

At Center for Neurology & Spine, we now offer specialized POTS testing in Phoenix, Arizona designed to identify the underlying cause of symptoms such as lightheadedness, palpitations, fatigue, brain fog, and exercise intolerance. Patients are evaluated by Mayo-trained neurologists Dr. Leslie Zuniga and Dr. Rebecca Jones, who focus on accurate diagnosis and individualized treatment of autonomic nervous system disorders.

If you are looking for POTS testing near you, autonomic testing in Arizona, or a neurologist for POTS diagnosis in Phoenix, CNS provides comprehensive, evidence-based evaluation to help you get clear answers and a path forward.

What is POTS

Postural Orthostatic Tachycardia Syndrome is a disorder of the autonomic nervous system, the part of the body responsible for regulating heart rate, blood pressure, temperature, and other involuntary functions.

In patients with POTS, the body has difficulty adjusting to standing. When moving from a lying or sitting position to standing, the heart rate increases abnormally, often by more than 30 beats per minute in adults, without a corresponding drop in blood pressure.

This leads to a range of symptoms that can be debilitating and unpredictable.

Common symptoms of POTS include

Rapid heartbeat or palpitations
Dizziness or lightheadedness when standing
Fainting or near-fainting episodes
Chronic fatigue
Brain fog or difficulty concentrating
Weakness
Exercise intolerance
Headaches or migraines
Nausea

Because these symptoms overlap with many other conditions, POTS is frequently misdiagnosed or dismissed, making proper neurologic evaluation essential.

Why POTS is Often Missed

Many patients with POTS are initially told they have anxiety, dehydration, or nonspecific fatigue. While those conditions can coexist, they do not fully explain the physiologic changes seen in autonomic dysfunction.

POTS requires objective testing to confirm. Without proper autonomic evaluation, patients may cycle through multiple providers without receiving a clear diagnosis.

At CNS, our goal is to shorten that diagnostic journey by providing targeted neurologic and autonomic testing in one setting.

Why Choose Center for Neurology & Spine for POTS Testing in Phoenix

Choosing the right neurologist for POTS diagnosis in Arizona matters. At CNS, we provide a focused, neurologist-led approach to autonomic disorders.

Symptoms That Should Prompt POTS Testing

Many patients are unsure when to seek evaluation. You should consider autonomic testing if you experience:

Persistent dizziness when standing
Rapid heart rate without clear cause
Feeling faint or actually fainting
Symptoms that worsen with heat or prolonged standing
Severe fatigue not explained by other conditions
Brain fog affecting work or school performance
Difficulty tolerating exercise

A key feature of POTS is that symptoms are positional, meaning they worsen when upright and improve when lying down.

How POTS Testing Works at CNS

Accurate diagnosis of POTS requires structured autonomic testing. At Center for Neurology & Spine, we perform comprehensive evaluations designed to measure how your body responds to positional change and physiologic stress.

Tilt Table Testing

This is the cornerstone of POTS diagnosis.

During this test

You are positioned on a motorized table
Your heart rate and blood pressure are monitored continuously
The table is tilted to simulate standing
Changes in cardiovascular response are recorded

A sustained increase in heart rate without significant blood pressure drop is suggestive of POTS.

Additional Autonomic Testing

Depending on symptoms, your neurologist may include:

Heart rate variability testing
Assesses autonomic balance between sympathetic and parasympathetic systems

Valsalva maneuver testing
Evaluates how your body regulates blood pressure during strain

Sudomotor testing
Measures sweat gland function, which is also controlled by the autonomic system

These tests help distinguish POTS from other causes of orthostatic intolerance such as neurocardiogenic syncope, dehydration, or medication effects.

What Makes CNS Testing Different

Many facilities only perform limited screening. At CNS, testing is integrated with neurologic expertise.

This means

Results are interpreted in clinical context, not in isolation
Subtle autonomic patterns are recognized
Overlapping neurologic conditions are considered
Treatment begins immediately after diagnosis

This comprehensive approach reduces misdiagnosis and improves outcomes.

Conditions That Can Mimic POTS

Accurate diagnosis requires ruling out other conditions with similar symptoms.

These include

Orthostatic hypotension
Cardiac arrhythmias
Anxiety disorders
Dehydration
Thyroid dysfunction
Chronic fatigue syndrome
Medication side effects

This is why neurologist-led evaluation is critical. POTS is a diagnosis that requires both clinical expertise and objective testing.

Treatment Options After Diagnosis

Once POTS is confirmed, treatment focuses on improving symptoms and restoring daily function.

Lifestyle Modifications

Many patients see improvement with structured changes:

Increased fluid intake
Higher salt intake when appropriate
Compression garments
Gradual exercise programs
Avoiding triggers such as prolonged standing or heat

Medication Options

Depending on severity, medications may be used to:

Control heart rate
Improve blood vessel tone
Increase blood volume
Stabilize autonomic signaling

Treatment is highly individualized, as POTS varies significantly between patients.

Ongoing Neurologic Care

At CNS, patients are not left with a diagnosis alone. Follow-up care includes:

Monitoring response to treatment
Adjusting therapy as needed
Managing coexisting neurologic symptoms such as headaches or neuropathy
Coordinating care when multiple systems are involved

Living With POTS in Arizona

Arizona presents unique challenges for patients with autonomic dysfunction.

Heat exposure can worsen symptoms by causing blood vessels to dilate, making it harder for the body to maintain blood pressure when standing.

Practical strategies include

Staying well hydrated year-round
Avoiding midday heat exposure
Using cooling strategies when outdoors
Gradually conditioning the body to tolerate activity

Education is a key part of long-term management, and CNS works closely with patients to develop sustainable routines.

When to Seek a Neurologist for POTS

If you have ongoing symptoms affecting your daily life, it is time to seek evaluation.

Early diagnosis can

Prevent unnecessary testing
Reduce symptom progression
Improve quality of life
Provide clarity after months of uncertainty

Searching for “POTS diagnosis Phoenix” or “autonomic testing near me” is often the first step. The next step is choosing a center with the expertise to provide real answers.

Frequently Asked Questions About POTS

What causes POTS

POTS can be triggered by infections, autoimmune conditions, hormonal changes, or may develop without a clear cause. In many cases, it involves dysfunction in how the autonomic nervous system regulates circulation.

Is POTS dangerous

POTS is not typically life-threatening, but it can significantly impact quality of life if untreated.

Can POTS be cured

There is no single cure, but many patients improve with proper treatment and lifestyle adjustments.

How is POTS diagnosed

Diagnosis is based on symptoms and confirmed through autonomic testing, particularly tilt table testing.

Do I need a neurologist for POTS

Yes. While other specialties may be involved, neurologists are trained to evaluate and diagnose autonomic nervous system disorders.
