Diagnostic tools and tests like electrocardiograms (ECG) allow us to gain valuable insight into the health of your furry companion. Here, our vets in East Setauket discuss ECGs for cats and dogs and how they can help us determine the heart health of pets.

What are ECGs for pets?

Have you heard of ECG? It stands for electrocardiogram, a heart-monitoring test that uses small sensors attached to the skin to observe the heart's electrical activity. This non-invasive method is used for both pets and humans.

If you're wondering about the cost of an ECG for your furry friend, it's best to consult with your vet for an accurate estimate. They can provide you with the information you need.

What will your vet learn from an ECG?

When your pet undergoes a feline or canine ECG, your vet gains valuable insight about their heart. This diagnostic tool reveals the heart's rate, rhythm, and electrical impulses within each section. The ECG pattern typically includes a small bump called the P wave, a large spike known as the QRS complex, and another small bump called the T wave.

The P wave represents atrial contractions, the QRS complex indicates ventricular depolarization (the typical heartbeat), and the T wave represents ventricular repolarization. The vet will pay close attention to the wave shape and distance between the various parts of the wave, with particular concern for the PR interval and QRS complex interval, which indicates how efficiently the heart is pumping blood.

Additionally, the vet will examine the distance between the peaks of the QRS complex to determine whether the heartbeat is regular or irregular. Finally, the number of QRS complexes over a certain time interval can be used to calculate the heart rate. It's important to note that the rate and rhythm of cats and dogs can vary, so consult your veterinarian to determine what values are expected for your pet.

Are ECGs a safe form of diagnostic testing?

Absolutely! ECG tests are completely safe and non-invasive. They passively monitor the heart and provide valuable diagnostic information.

When are ECGs needed?

If your vet has noticed any signs that indicate potential heart disease during a routine exam they may choose to perform an ECG. These may include:

  • Irregular heartbeat
  • Heart murmur (which indicates turbulent blood flow over a valve within the heart)
  • Irregular pulses
  • Abnormal lung sounds

Pre-Anesthetic Evaluation

It can be beneficial to have a thorough comprehension of a dog or cat's cardiovascular health before administering anesthesia. This will help to determine how safe it may be and if your pet has any conditions that might increase the risk of complications.

What is considered a normal cat or dog ECG?

You may be wondering what a normal canine or feline ECG is. Overall, this depends on the type of pet you have. The normal heart rates for dogs and cats are as follows:

Dog: The normal rhythm for a canine is typically 60 to 170 beats per minute.

Cat: The normal rhythm of felines should be 140 to 220 beats per minute.

How much is an ECG for a dog or cat?

As with many other veterinary care services, the cost of your dog or cat's ECG will vary from clinic to clinic and from pet to pet. This is because several different factors contribute to the final cost.

This can be the location of the clinic and the expertise of the practitioner, the type of equipment used, and any additional tests required. The age and species of your pet also play a role in the final amount that you will pay.

Your vet will be able to provide you with an accurate estimate for the expected cost of your pet's diagnostic testing.
