ARRHYTHMOGENIC RIGHT VENTRICULAR CARDIOMYOPATHY (ARVC) IS A FAIRLY COMMON FORM OF HEART DISEASE IN THE BOXER DOG.
Arrhythmogenic right ventricular cardiomyopathy (ARVC), formerly known as Boxer cardiomyopathy, runs in families of Boxers, and has been reported in humans and cats as well. It has been shown to be genetic, so affected animals should not be bred. Affected animals suffer from ventricular arrhythmias, or abnormal heart beats which originate from the right ventricle (one of the bottom chambers of the heart). In addition, affected animals may also have enlargement of the right side of the heart, systolic dysfunction (decreased ability to pump blood forward to the body), and congestive heart failure. Often the first sign that is seen is sudden death during exercise or even while sleeping.
