Arrhythmogenic right ventricular cardiomyopathy is an inheritable form of myocardial disease characterized most commonly by ventricular tachycardias, syncope, and sometimes systolic dysfunction and heart failure. A genetic mutation in the striatin gene has been identified in many affected dogs. Dogs with only one copy of the mutation (heterozygous) have a variable prognosis, with many dogs remaining asymptomatic or being successfully managed on antiarrhythmic drugs for years. Dogs that are homozygous for the mutation seem to have a worse prognosis.
