Synonyms for ARVD include Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) and Arrhythmogenic Right Ventricular Disease (ARVD/C). Other terms used to describe this condition include right ventricular cardiomyopathy, right ventricular dysplasia, and right ventricular arrhythmia syndrome. While these terms may differ slightly, they all describe the same disease affecting the right side of the heart. ARVD is a serious condition that can lead to sudden cardiac death, and it is important to seek medical attention if any symptoms are present.
