The best starting point for POTS is your primary care doctor, who can run initial tests and refer you to a specialist. For ongoing management, most people with postural orthostatic tachycardia syndrome end up seeing an autonomic neurologist, a cardiologist, or both. The specific specialist you need depends on your symptoms, your subtype, and what’s available in your area.
Start With Your Primary Care Doctor
A primary care physician can do quite a lot before you ever see a specialist. The initial workup typically includes a physical exam, orthostatic vital signs (your heart rate and blood pressure measured while lying down and then at intervals after standing), and a 12-lead electrocardiogram. Blood work should screen for secondary causes of an elevated standing heart rate, including thyroid function, iron levels, electrolytes, kidney function, and morning cortisol. A 24-hour Holter monitor can also be ordered to track your heart rhythm over a full day.
This minimal approach is often enough to establish a working diagnosis and even start treatment. The diagnostic threshold is a heart rate increase of at least 30 beats per minute within 10 minutes of standing in adults, or 40 beats per minute in adolescents, without a significant drop in blood pressure. If your doctor confirms those numbers and your symptoms line up, you don’t necessarily need a specialist to begin basic management. Specialist referral becomes important when the diagnosis is uncertain or when first-line treatments aren’t helping.
Autonomic Neurologists
An autonomic neurologist is the most targeted specialist for POTS. These are neurologists with additional training in disorders of the autonomic nervous system, the part of your nervous system that controls things like heart rate, blood pressure, sweating, and digestion without you thinking about them. They’re relatively rare. Brigham and Women’s Hospital describes their POTS clinic as staffed by “some of the nation’s few neurologists certified in autonomic disorders.”
What sets autonomic neurologists apart is access to specialized testing. A full autonomic workup can include a tilt table test, where you’re strapped to a table tilted to about 60 degrees for up to 30 minutes while your heart rate and blood pressure are continuously recorded. It can also include a quantitative sudomotor axon reflex test, which measures the function of the nerves that control sweating, and a thermoregulatory sweat test that maps your sweat pattern across your body. These tests help identify which part of your autonomic nervous system is affected and how severely, which directly shapes treatment.
Autonomic neurologists are especially valuable if your POTS may involve nerve damage. In neuropathic POTS, partial damage to the small nerves that control blood vessel tone causes blood to pool in the legs, and the heart speeds up as a compensatory reflex. Identifying this subtype matters because treatments that work for one form of POTS can actually be harmful in another.
Cardiologists and Electrophysiologists
Cardiologists are frequently the first specialists POTS patients see, since the most obvious symptom is a rapid heart rate. A general cardiologist can evaluate your heart structure and function, rule out other cardiovascular causes of your symptoms, and manage medications that target heart rate or blood volume.
An electrophysiologist is a cardiologist who subspecializes in heart rhythm disorders. Their role in POTS is primarily to rule out other causes of a fast heart rate. The tachycardia in POTS originates from the sinus node, your heart’s natural pacemaker, so it needs to be distinguished from abnormal electrical pathways or reentrant rhythms that cause the heart to race in a different way. An ECG and sometimes a Holter monitor can sort this out. If a separate rhythm disorder is found, it may need its own treatment before POTS can be properly diagnosed.
One important note from the American Heart Association: radiofrequency modification of the sinus node to treat the fast heart rate in POTS is not recommended. It often makes symptoms worse and can occasionally leave patients dependent on a pacemaker.
Why Your Subtype Matters
POTS isn’t one condition with one cause. The hyperadrenergic subtype involves excessive activation of the sympathetic nervous system, your body’s fight-or-flight response, as the primary driver. These patients often experience flushing, blood pressure spikes on standing, and surges of adrenaline. In contrast, neuropathic POTS involves nerve damage, and the sympathetic activation is a compensatory response the body needs to maintain blood pressure upright.
This distinction has direct treatment implications. Medications that calm the sympathetic nervous system can help hyperadrenergic patients but would be contraindicated in neuropathic patients who depend on that same activation to keep blood flowing to their brain. Research from the Vanderbilt Autonomic Dysfunction Center highlights that autonomic specialists use specific testing, including catecholamine levels and responses during the Valsalva maneuver, to distinguish these subtypes. If your symptoms are complex or you’re not responding to initial treatment, getting this level of evaluation can change your care plan significantly.
The Multidisciplinary Team
POTS affects far more than heart rate. Many patients deal with fatigue, brain fog, digestive problems, exercise intolerance, and sleep disruption. Dedicated POTS clinics, like those at Cleveland Clinic, Brigham and Women’s, and Vanderbilt, bring together a broader care team that can include physical therapists, nutritionists, and psychotherapists alongside the core neurologists and cardiologists. Physical therapy in particular plays a central role, since structured exercise programs are one of the most effective long-term treatments for POTS.
If your symptoms extend beyond cardiovascular issues, you may also benefit from seeing a gastroenterologist for digestive problems or an endocrinologist if hormonal factors are suspected. Your autonomic specialist can help coordinate these referrals.
How to Find a POTS-Literate Doctor
One of the biggest challenges is simply finding a provider who understands POTS. Dysautonomia International maintains a physician directory with regional listings and an interactive global map of doctors experienced in autonomic disorders. This is often the most efficient way to find someone near you who won’t require extensive education about the condition before they can help.
Wait times for specialized autonomic clinics can be long, sometimes months. A few practical strategies can help you make the most of that waiting period. Some programs, including Cleveland Clinic’s POTS program, offer virtual visits for initial evaluations and follow-ups, which eliminates travel and can sometimes shorten wait times. While you wait, your primary care doctor can begin basic interventions like increasing salt and fluid intake, compression garments, and a gradual exercise program.
Preparing for Your Appointment
Before your first specialist visit, tracking your own data at home gives your doctor something concrete to work with. The CDC’s orthostatic vital signs format is a useful template: lie down for five minutes, then record your blood pressure and heart rate. Stand up and record both again at one minute and three minutes, noting any symptoms like dizziness, pounding heart, nausea, or visual changes at each time point. Do this at different times of day over a week or two.
Bring a list of all your current medications and supplements, since some can affect heart rate and blood pressure readings. Note when your symptoms started, what makes them worse (heat, meals, menstrual cycle, prolonged standing), and any conditions you’ve already been diagnosed with. If previous doctors have run blood work, an ECG, or a Holter monitor, bring those results. Specialists at autonomic clinics see patients with complex histories, and arriving with organized information helps them focus the visit on what you actually need rather than repeating tests you’ve already had.
