Did you know that over 50% of the Dobermans develop devastating heart disease, Dilated Cardiomyopathy? While majority are over 6 years of age, some Dobermans are under 2 years old. There are many genetic and environmental factors that contribute to DCM, with numerous studies underway to better understand this significant disease. DCM frequently progresses to heart failure. However, about 30% of the affected Dobermans may not show any clinical signs before succumbing to sudden cardiac death. This is a devastating and in many cases preventable situation. We can help you catch DCM early via a combination of genetic screening, auscultation, x-ray monitoring, echocardiogram (cardiac ultrasound), monitoring heart enzymes, and general DCM counseling. At RBAH, we offer Holter Monitoring – an indispensable tool in early detection of abnormal heart beat that can lead to sudden death. To our knowledge, we are the only Practice in the region with this equipment. Holter reports are handled by the Alba Medical, our partners in heart health.
We developed interest in canine DCM due to our heavy Doberman Pinscher patient load and lack of Board-Certified Cardiology service in the Memphis area. 24-hour Holter Monitoring could be a lifesaving tool because it allows for early detection and management of arrhythmias – like in both Dr. Lapova’s personal Dobermans. It is also an invaluable tool for preservation breeders which aids in proper breeding selection. We advise any potential puppy buyer consider whether the breeder has properly tested and tracked heart health in their program. Other breeds commonly Holter monitored are Boxer, Cavalier King Charles Spaniel, Cane Corso, Great Dane, Cocker Spaniel, Bouvier de Flanders, Bull Mastiff, German Shepherd, Golden Retriever, Rottweiler, Great Pyrenees, Irish Wolfhound, Saluki, Labrador Retriever, Newfoundland, Old English Sheepdog, Beauceron, Rhodesian Ridgeback – or any dog with history or suspicion of cardiac arrhythmia.
European Society of Veterinary Cardiology Screening Guidelines for DCM in Doberman Pinschers recommend annual screening with both Holter and echocardiogram beginning at 3 years of age*. We have detected arrhythmias in Dobermans much younger. Genetic testing and ancillary biomarkers such as NT-pro BNP and cTnl could also be helpful; however, a recent study*** showed 6/48 affected Dobermans has no genetic markers for DCM1 or DCM2. There is no substitute for 24-hour Holter monitoring and echocardiogram. Please note that 5-minute ECG lacks sensitivity and specificity for ventricular ectopy detection. Combining Holter Monitor with NT-pro BNP can also be useful for oDCM detection**
You don’t have to be an RBAH Client to rent the Holter monitor. We are happy to work with your Veterinarian to outfit the dog with the monitor and submit the report. You can work with your family Veterinarian or Cardiologist to generate the best treatment plan for your dog. Have a Heart – Holter! Please feel free to call with any questions, or have your Veterinarian give us a call!
