What Is Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)?

ARVC is an inherited condition where heart muscle tissue weakens and is replaced with fatty or fibrous material. This disrupts normal electrical signals and raises the risk of irregular rhythms. Symptoms appear in adolescence or adulthood. Early evaluation helps guide long-term safety planning.

What Causes ARVC?

ARVC results from inherited changes that weaken heart muscle structure. Over time, muscle cells break down and are replaced with fatty or fibrous tissue. This disrupts electrical signals and creates rhythm problems. Symptoms often appear during exercise or stress.

Common Symptoms

Irregular heartbeat, dizziness, fainting, chest discomfort, and shortness of breath appear frequently. Some individuals experience palpitations during activity. Severity differs across cases.

How Is ARVC Diagnosed?

Diagnosis includes heart imaging, rhythm monitoring, and genetic testing. Doctors review exercise history and fainting episodes. Long-term monitoring helps track rhythm changes. Care plans adjust with symptoms. Family testing is often recommended.

How Does ARVC Affect Daily Life?

Individuals adjust activity levels to avoid rhythm problems. Fatigue affects work, exercise, and daily routines. Regular monitoring becomes part of life. Some people avoid heavy exertion. Support helps manage long-term stress.

What Treatment Approaches Are Used?

Care includes rhythm monitoring, activity changes, and medication to stabilize heart signals. Devices support rhythm control for some individuals. Doctors track symptoms over time. Support focuses on safety during exertion. Family testing helps identify risks.

When to See Your Doctor

If something feels off or your symptoms stick around longer than expected, it's a good idea to get checked. Sudden changes, discomfort that doesn't improve, or anything that affects your daily routine deserve attention. A doctor can help figure out what's going on and guide you on the right next steps.
