Living with Familial atrial fibrillation

An inherited heart rhythm condition with a fast, irregular heartbeat and a higher risk of stroke.

Understanding Familial atrial fibrillation

Familial atrial fibrillation is an inherited heart condition that disrupts the heart's rhythm.

Erratic electrical activity in the upper heart chambers causes a fast, irregular heartbeat. It often starts in adulthood. Complications can occur at any age, though some people never have health problems. It also raises the risk of stroke.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Fast, irregular heartbeat (palpitations)
  • Dizziness
  • Chest pain
  • Shortness of breath
  • Fainting
  • Tiredness (fatigue)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists and heart and blood vessel specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
