Living with Arrhythmogenic right ventricular cardiomyopathy

A heart muscle disease that usually appears in adulthood and can cause abnormal heartbeats.

Understanding Arrhythmogenic right ventricular cardiomyopathy

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a form of heart disease in which part of the heart muscle gradually breaks down.

It usually appears in the teen years or adulthood. The breakdown of heart muscle (myocardium) raises the chance of an abnormal heartbeat (arrhythmia). It may cause no symptoms early on. Over time it can cause shortness of breath and swelling in the legs or belly, and later heart failure.

Signs & symptoms

GARD describes these symptoms when they occur:

  • Fluttering or pounding in the chest (palpitations)
  • Light-headedness
  • Fainting (syncope)
  • Shortness of breath
  • Swelling in the legs or belly

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.

  4. Connect with expert centers

    SADS Foundation, LMNA Cardiac Diseases Network and Children's Cardiomyopathy Foundation may keep lists of experts for this condition.
