After visiting Iditarod Elementary today, Terrie and I swung over to the Iditarod Headquarters to see what was going on at the vet trailer. We pulled in at just the right time. A musher was there getting the required EKG’s done on his team. I thought this might be a good opportunity to explain a little more about an EKG.
What is an EKG?
The letters EKG stand for electrocardiogram. An EKG is a non-invasive, completely painless test, which evaluates the health of a dog’s heart. It measures the heart rate and heart’s electrical activity to tell the veterinarian if the dog has an irregular or dangerous heartbeat that can’t be detected with a stethoscope.
How is the test done?
The dog lies on a table and clips with wires coming from them are attached to the dog in several locations. The musher or handler stays at the dog’s head to keep the dog calm. The wires are attached to a special recording machine. During the EKG, electrical signals from the dog’s heart are sent through the wires to the EKG machine. The EKG machine records a reading of the dog’s heart rate and electrical activity on paper. This only takes about 2-3 minutes.
Does it hurt?
No, an EKG is painless. After the EKG is completed, the clips are removed and there are no marks on the dog.
Does every dog in the Iditarod get an EKG?
Yes, every dog is required to get an EKG before racing in the Iditarod Sled Dog Race.
Can a dog be disqualified from participating based on an EKG?
Yes. The chief veterinarian has the authority to deny entry of any dog to the race if the dog has an abnormality which may put the dog at risk for injury or death.
Are EKG’s done on humans?
Yes. EKG’s are performed on humans for the same reasons they are performed on dogs.
Keep in mind that an EKG is only one part of the overall vet care these world class athletes (the dogs) receive. The dogs get a blood test, worming, complete physical and each dog is micro chipped. During the race each musher is required to carry a vet book in which is recorded any observations that may require special attention. The veterinarian and the musher must both sign the vet book before the musher leaves the checkpoint.
