The purpose of this study is to collect information about patients with Arrhythmogenic right ventricular cardiomyopathy(ARVC) and about the disease. ARVC is a rare condition that affects heart muscle and causes abnormal heart rhythms (this is called "arrhythmia"). Participation in this study will take about 5 years. If your study doctor determines you are eligible and you agree to participate, you will be asked to visit the study doctor's office as part of your regular care for a screening visit and about 1 time each year for the length of the study. The majority of the data collected for this study will be part of your regular care, however study related procedures include arrhythmia monitoring, using wearable devices to measure tracing of the electrical activity of your heart, blood work, including genetic testing, and patient questionnaires
