Understanding Heart Palpitations and Conquering Atrial Fibrillation

May 12, 2023

Heart palpitations can be a cause of concern for many individuals, often leading to questions about their significance and potential underlying conditions. One such condition is Atrial Fibrillation (Afib), a common cardiac rhythm disorder that affects millions of people worldwide.

In this blog post, we will explore the nature of heart palpitations, delve into the details of Atrial Fibrillation, its causes, associated risks, and shed light on how Functional Medicine approaches this condition.

  1. What is a heart palpitation and are they all actually abnormalities?

    Heart palpitations are sensations of rapid, irregular, or fluttering heartbeats that can be felt in the chest, throat, or neck. While palpitations may often feel alarming, not all instances are indicative of underlying abnormalities. In fact, occasional palpitations can be a normal response to emotions, physical activity, caffeine, or hormonal changes. However, persistent, frequent, or concerning palpitations should be evaluated by a healthcare professional.

  2. What is Atrial Fibrillation (Afib) and how common is it?

    Atrial Fibrillation is a type of cardiac arrhythmia characterized by irregular and often rapid electrical impulses in the upper chambers (atria) of the heart. This disruption affects the heart's ability to pump blood efficiently. Afib is one of the most prevalent cardiac rhythm disorders, affecting an estimated 33 million individuals globally. Its prevalence increases with age, and it is more common in individuals with pre-existing heart conditions, high blood pressure, or other cardiovascular risk factors.

  3. What causes Atrial Fibrillation?

    Atrial Fibrillation can have various causes, including:

  • Age: Advancing age is a significant risk factor for Afib.
  • High Blood Pressure: Chronic hypertension puts strain on the heart, increasing the risk of rhythm abnormalities.
  • Heart Disease: Conditions such as coronary artery disease, heart valve disorders, or previous heart surgeries can predispose individuals to Afib.
  • Thyroid Disorders: Both an overactive thyroid (hyperthyroidism) and an underactive thyroid (hypothyroidism) can contribute to the development of Afib.
  • Alcohol and Substance Abuse: Excessive alcohol consumption, stimulant use, and illicit drug abuse can trigger or exacerbate Afib.
  • Sleep Apnea: Untreated sleep apnea may disrupt normal heart rhythms, potentially leading to Afib.
  1. How can Atrial Fibrillation cause strokes?

    Atrial Fibrillation significantly increases the risk of stroke due to the formation of blood clots. In Afib, the irregular and rapid electrical impulses can cause blood to pool and stagnate in the atria, leading to the formation of clots. If a clot dislodges and travels to the brain, it can block blood flow, resulting in an ischemic stroke. Consequently, individuals with Afib are often prescribed blood-thinning medications (anticoagulants) to prevent clot formation and reduce the risk of stroke.

  2. Why is Atrial Fibrillation considered to be a "lifestyle disease"?

     Atrial Fibrillation is often referred to as a "lifestyle disease" because various lifestyle factors can contribute to its development and progression. Sedentary lifestyle, poor dietary choices, obesity, excessive alcohol consumption, smoking, and unmanaged stress can all increase the risk of Afib. Adopting a healthier lifestyle, including regular physical activity, a balanced diet, stress management, and avoiding excessive alcohol and tobacco, can help prevent or manage Afib.

  3. How is Atrial Fibrillation diagnosed?

    Diagnosing Atrial Fibrillation typically involves a combination of medical history assessment, physical examination, and diagnostic tests such as:

  • Electrocardiogram (ECG): This test records the electrical activity of the heart and can detect irregularities in heart rhythm.
  • Holter Monitor: A portable ECG device worn for 24-48 hours to monitor heart activity continuously, allowing for the detection of intermittent Afib episodes.
  • Event Monitor: Similar to a Holter monitor, but worn for a longer duration, typically up to 30 days. It is activated by the individual when they experience symptoms to capture any arrhythmias.
  • Echocardiogram: This imaging test uses ultrasound waves to create a visual representation of the heart's structure and function, helping identify underlying heart conditions that may contribute to Afib.
  • Blood tests: These can help assess thyroid function, electrolyte levels, and other potential contributing factors.

    It is important to consult with a healthcare professional for an accurate diagnosis and appropriate treatment plan.

    7. What can be done about Atrial Fibrillation from a Functional Medicine perspective?

Functional Medicine takes a comprehensive and personalized approach to address the underlying imbalances contributing to Afib. Some strategies that may be considered include:

  • Identifying and addressing nutritional deficiencies, such as magnesium or potassium, which are essential for normal heart rhythm.
  • Managing inflammation through dietary modifications that focus on whole, nutrient-dense foods and reducing processed foods and sugar.
  • Implementing stress reduction techniques, such as mindfulness, meditation, and relaxation exercises, to support heart health.
  • Optimizing sleep quality and addressing underlying sleep disorders, such as sleep apnea.
  • Supporting overall cardiovascular health through regular physical activity and tailored exercise plans.
  • Assessing and addressing other underlying conditions, such as hormonal imbalances or gut health issues, which may contribute to Afib..

Atrial Fibrillation is a common cardiac rhythm disorder that can have significant impacts on an individual's health and quality of life. Understanding the causes, risks, and lifestyle factors associated with Afib is crucial for prevention, early detection, and management. By combining conventional medical interventions with a Functional Medicine perspective, individuals with Afib can explore comprehensive strategies to address underlying imbalances and promote heart health. Always consult with healthcare professionals for accurate diagnosis, personalized treatment plans, and ongoing care.
