This will also provide a baseline for comparison once treatment has started. If they suspect cardiac disease, a heart monitor may be placed on your dog to determine the complexity and severity of the arrhythmia. If the disease is causing congestive heart failure, your veterinary cardiologist will likely recommend starting treatment right away. Some dogs seem to show improvement with the use of l-carnitine, a supplement used to increase levels of carnitine, which stimulates fatty-acid oxidation and is essential to a fully-functioning body. Generally, treatment consists of antiarrhythmic agents (medications) unless there is evidence of congestive heart failure or other problems with the heart. Your veterinarian will want to try to normalize the heartbeat as one of the first priorities of treatment. Unfortunately, histopathology, which is conducted post-mortem, is still widely accepted as the best method of diagnosing the disease.Ī thoracic radiograph (chest X-ray) may help to determine whether there is enlargement of the heart or other evidence of heart failure.

24-hours ambulatory ECG Holter monitoring (worn by the dog to record heart rhythm for a few days).

Echocardiography (to rule out any other cardiac disease).

The following tests and tools to test for and diagnose arrhythmias and ARVC in your Boxer: Your veterinary cardiologist will need a thorough history of your pet's health leading up to the onset of symptoms, including any information you may have about your dog's family background. We offer state-of-the-art cardiology services, diagnostics and procedures for the assessment of heart conditions in cats and dogs at our two locations in Long Island. Our board-certified veterinary cardiologist at Atlantic Coast New York Veterinary Specialists is trained to diagnose cardiovascular diseases in pets. Another challenge is that sudden death may be the first and only clinical symptom. The disease can also mimic other cardiac diseases such as dilated cardiomyopathy. Unfortunately, ARVC is difficult to diagnose for a few reasons, but primarily because dogs may be asymptomatic between arrhythmias.

How is cardiomyopathy in Boxers diagnosed? Collapse (especially during or after exercise).

Irregular heartbeat (which a veterinarian may notice during a routine exam.What are symptoms of cardiomyopathy in Boxers?įor Boxers with cardiomyopathy, symptoms can be very serious and may vary. In one study, 50% of Boxers were positive for the gene that causes ARVC. How often do Boxers experience cardiomyopathy?ĪRVC disease is very common in Boxers. Even if your dog is negative, it does not mean that heart disease or an arrhythmia will never develop just as there are many genetic causes for the disease in people, this could also be true in Boxers. Up to 40% of Boxers have a genetic mutation in an important heart gene (striatin) with a characteristic called "incomplete penetrance", which means that even if a dog has the mutation it may not penetrate and result in the disease developing.Ī DNA test can determine whether your dog has the mutation. The arrhythmia can often (but not always) be detected during a physical examination in dogs that are affected. The condition generally develops in middle-aged (5 to 7 years old) dogs. If VPCs occur sequentially, an arrhythmia called ventricular tachycardia occurs and can cause symptoms. These early abnormal heartbeats originate from the heart muscle instead of the specialized conduction tissue in the heart, where normal heart beats originate.

The specific arrhythmia related to this disease is called ventricular premature complies (VPC). This leads to electrical instability in the heart muscle and heart arrhythmias (irregular heart rhythm), which can seriously affect the heart and cause a dog to faint, collapse or even die suddenly. With ARVC, normal heart muscle is replaced with fibrous, fatty tissue. Also referred to as Boxer Cardiomyopathy, this disease rarely affects other breeds. What is cardiomyopathy (ventricular arrhythmia) in Boxers?Īrrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetic disease that appears in adult Boxer dogs.
