What specialty is best for managing Postural Orthostatic Tachycardia Syndrome (POTS)?

Cardiology is the Primary Specialty for Managing POTS Syndrome

Patients with Postural Orthostatic Tachycardia Syndrome (POTS) should be primarily managed by a cardiologist, specifically one with expertise in autonomic disorders or electrophysiology. 1

Understanding POTS and Specialty Care Needs

POTS is defined as a clinical syndrome characterized by:

• An increase in heart rate of ≥30 bpm (≥40 bpm in ages 12-19) during positional change from supine to standing
• Absence of orthostatic hypotension (>20 mm Hg reduction in systolic BP)
• Frequent symptoms occurring with standing (lightheadedness, palpitations, tremulousness, weakness, blurred vision)
• Symptoms lasting for >6 months

Why Cardiology is the Primary Specialty

The American College of Cardiology/American Heart Association/Heart Rhythm Society guidelines include POTS within their scope of practice 1. This reflects the fundamental cardiovascular nature of the condition, which centers on abnormal heart rate response to postural change.

Multidisciplinary Management Approach

While cardiology serves as the primary specialty, POTS often requires involvement from other specialists based on specific symptoms:

1. Cardiology: Primary management of orthostatic tachycardia, hemodynamic abnormalities, and cardiovascular symptoms

   • Focus on heart rate control and volume regulation
   • Expertise in differentiating POTS from other cardiac conditions

2. Neurology: When autonomic neuropathy is suspected or neurological symptoms predominate

   • Evaluation of partial autonomic neuropathy
   • Management of neurological manifestations

3. Gastroenterology: For patients with significant GI symptoms

   • Management of bloating, nausea, diarrhea, abdominal pain 1

4. Endocrinology: When volume dysregulation is prominent

   • Management of hypovolemia
   • Assessment of hormonal factors affecting blood volume

Treatment Algorithm by Pathophysiologic Mechanism

Treatment should be directed by the predominant pathophysiologic mechanism 2:

1. Partial Neuropathic POTS:

   • Compression stockings and abdominal binders
   • Vasoconstrictors (midodrine)

2. Hypovolemic POTS:

   • Structured exercise program
   • Increased salt/fluid intake
   • Fludrocortisone

3. Hyperadrenergic POTS:

   • Beta-blockers
   • Avoidance of norepinephrine reuptake inhibitors

Common Pitfalls in POTS Management

1. Misdiagnosis: POTS can be misdiagnosed as anxiety or deconditioning. A cardiologist with expertise in autonomic disorders is best positioned to make an accurate diagnosis.

2. Delayed Referral: Patients often see multiple specialists before receiving appropriate diagnosis and treatment. Early referral to cardiology can prevent this delay.

3. Inadequate Treatment: Treatment is often inconsistent and unstandardized 3. A cardiologist familiar with POTS can provide evidence-based management.

4. Overlooking Comorbidities: POTS often overlaps with conditions like Ehlers-Danlos syndrome, chronic fatigue syndrome, and mast cell activation syndrome 4. A cardiologist should coordinate care with other specialists when these comorbidities are present.

5. Post-COVID POTS: Recent evidence shows 2-14% of COVID-19 survivors develop POTS 5. Cardiologists are increasingly managing this emerging presentation.

Conclusion

While POTS management often requires a multidisciplinary approach, cardiology should serve as the primary specialty coordinating care, with specific expertise in autonomic disorders being particularly valuable. This approach ensures proper diagnosis, appropriate treatment targeting the underlying pathophysiologic mechanisms, and coordination of multidisciplinary care when needed.
