Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetic cardiomyopathy resulting from disordered function of the intercalated discs with mainly arrhythmic manifestation, which can be difficult to diagnose because of its variable presentation. The incidence of ARVC is reported to be 1:2000 to 1:5000.

Hypertrophic cardiomyopathy (HCM)-related sudden cardiac death (SCD) rates with contemporary management are low; however, high-intensity exercise can induce fatal arrhythmias in HCM patients. Thus, current guidelines recommend avoiding high-intensity exercise in HCM patients at high risk for SCD1,2.
