Can AFib and POTS Be Treated Simultaneously?

Living with a heart condition is challenging enough, but managing two complex conditions like AFib and POTS simultaneously can feel overwhelming. Atrial Fibrillation (AFib) and Postural Orthostatic Tachycardia Syndrome (POTS) are both disorders involving the heart’s rhythm and the autonomic nervous system, yet they differ significantly in causes, symptoms, and treatment approaches. But is it possible to treat both at the same time? The answer is — yes, with careful coordination and individualised care.

In this article, we’ll explore how AFib and POTS can coexist, what makes their treatment complex, and how healthcare providers manage both conditions together.

Understanding AFib and POTS

AFib (Atrial Fibrillation) is a common type of arrhythmia where the heart beats irregularly and often rapidly. It results from chaotic electrical signals in the upper chambers of the heart (atria), which lead to inefficient blood flow. People with AFib are at increased risk of stroke, heart failure, and other heart-related complications.

POTS (Postural Orthostatic Tachycardia Syndrome), on the other hand, is a form of dysautonomia — a disorder of the autonomic nervous system. POTS causes an excessive heart rate increase when standing up, accompanied by symptoms such as dizziness, palpitations, fatigue, and even fainting. Unlike AFib, POTS does not directly increase the risk of stroke, but significantly affects quality of life.

Although AFib and POTS are separate conditions, some patients may experience both simultaneously. This overlap requires a thoughtful and nuanced treatment approach.

Can AFib and POTS Be Treated at the Same Time?

Yes, but with caution. Treating AFib and POTS together is possible, though it presents unique challenges. Both conditions involve heart rhythm disturbances, but their triggers and treatment goals differ.

• AFib management focuses on controlling the heart rate, restoring a normal rhythm, and preventing strokes.
• POTS treatment emphasises stabilising blood pressure, controlling heart rate upon standing, and improving autonomic function.

Because some medications used for AFib may worsen POTS symptoms — and vice versa — a comprehensive, tailored treatment plan is essential.

Key Considerations in the Combined Treatment Approach

1. Collaborative Care with Specialists

Managing AFib and POTS together often requires a multidisciplinary team, including cardiologists, electrophysiologists, and neurologists. This ensures all aspects of both conditions are considered when creating a treatment plan.

2. Medication Management

• Beta-blockers are commonly used for both conditions. They help slow the heart rate in AFib and may also reduce the heart rate response in POTS. However, some patients with POTS may not tolerate beta-blockers well due to low blood pressure.
• Calcium Channel Blockers may be considered in AFib patients, but need to be carefully evaluated in POTS cases.
• Ivabradine, a heart rate-reducing medication, is sometimes used off-label for POTS and may help with AFib rate control in select cases.
• Anticoagulants are essential in AFib to prevent stroke, but have no role in POTS. Care must be taken if a patient with POTS is prone to fainting, as anticoagulants increase bleeding risk.

Medication regimens must be closely monitored to avoid exacerbating symptoms of either condition.

3. Lifestyle Modifications

Lifestyle adjustments can play a significant role in managing both AFib and POTS:

• Hydration and Salt Intake:
  Essential for POTS patients to maintain blood volume and stabilise blood pressure. This may also indirectly help in AFib by preventing dehydration, a known trigger.
• Exercise Therapy:
  Graded exercise programs are a cornerstone of POTS management. However, certain types of exercise may trigger AFib episodes, so an individualised exercise plan under medical supervision is crucial.
• Avoiding Triggers:
  Identifying and avoiding known triggers (caffeine, alcohol, stress) can benefit both conditions.

4. Catheter Ablation — A Consideration for AFib

For patients with drug-resistant AFib, catheter ablation — a procedure that destroys the areas of the heart causing abnormal rhythms — may be recommended. While catheter ablation is not a treatment for POTS, stabilising AFib through this procedure may reduce the overall cardiovascular burden, potentially making POTS symptoms easier to manage.

What’s the Treatment Process Like?

The treatment process for managing AFib and POTS together typically involves:

1. Comprehensive Evaluation — Thorough cardiac testing, autonomic function tests, and detailed symptom analysis.
2. Developing a Customised Plan — Prioritising safety, managing medications, and considering the interplay between both conditions.
3. Close Monitoring and Adjustments — Regular follow-ups to monitor the effects of treatment on both AFib and POTS symptoms.
4. Patient Education and Support — Equipping patients with knowledge about symptom tracking, medication adherence, and lifestyle strategies.

Conclusion

Managing AFib and POTS together is complex but entirely possible with a carefully crafted, patient-centred approach. The key lies in balancing treatments that control heart rhythm without worsening autonomic symptoms. Collaboration between healthcare providers and patients, open communication, and continuous monitoring make simultaneous treatment achievable and effective.

If you or someone you know is dealing with both AFib and POTS, consult a specialised care team experienced in treating both conditions. With the right guidance, living a balanced life with both diagnoses is within reach.
