What is Atrial Fibrillation (AFib) In Pets?

Today, we at Coast to Coast Cardiology are discussing a type of arrhythmia called Atrial fibrillation (AFib). AFib is a common heart rhythm disorder that affects both humans and animals. In dogs and cats, It can be especially debilitating and impact their quality of life.

Understanding this condition is important for pet owners to recognize symptoms, so let’s unpack it in detail.

Explaining Atrial Fibrillation

The heart has four chambers: two upper chambers (atria) and two lower chambers (ventricles). Atrial fibrillation occurs when the upper chambers of the heart beat irregularly instead of in a coordinated manner. This irregular rhythm can disrupt blood flow and reduce the heart’s efficiency in pumping blood.

While pets of all ages and breeds can develop atrial fibrillation, certain factors increase the risk. Underlying heart conditions, such as dilated cardiomyopathy or valvular disease, often contribute to this arrhythmia by disrupting the heart’s electrical system.

Additionally, metabolic disorders like hyperthyroidism in cats can strain the heart and increase susceptibility. Age-related changes to the heart muscle and the development of other health issues like hypertension further elevate the risk for older pets.

Symptoms of AFib in Pets

Symptoms can vary and may not always be apparent. Some common signs include:

  • Lethargy or weakness
  • Coughing
  • Difficulty breathing
  • Decreased exercise tolerance
  • Collapse or fainting

It’s important to note that these symptoms can also be associated with other health conditions, so a thorough veterinary examination is necessary for accurate diagnosis.

Diagnosis and Treatment

Because it’s an arrhythmia, diagnosing AFib typically includes listening to the heart’s rhythm with a stethoscope. Additional tests, such as electrocardiograms (ECGs) and echocardiograms, may be required to confirm the diagnosis and assess the severity of the condition.

Treatment for AFib depends on the severity of symptoms and underlying causes. Some pets may require medication to regulate heart rhythm or control heart rate. In severe cases, surgical procedures may be considered.

Regular monitoring and follow-up care are essential for managing AFib, so consult with a trusted veterinarian for a treatment plan tailored to your pet’s specific needs.

Prevention and Management

While there’s no guaranteed way to prevent AFib, helping your pet maintain a healthy weight, regular exercise, and a balanced diet can help support their cardiovascular health.

If you notice any signs of lethargy, difficulty breathing, or other concerning symptoms in your pet, it’s important to consult with your veterinarian immediately. Early diagnosis and treatment can mean more time spent in the long run with your friend.
