Understanding Cardiac Arrhythmia in Cats
When it comes to feline health, it’s important to be aware of potential conditions that can affect our furry friends. One such condition is cardiac arrhythmia, which refers to an irregular heartbeat in cats. Understanding the basics of cardiac arrhythmia can help cat owners identify potential issues and seek appropriate veterinary care.
What is Cardiac Arrhythmia?
Cardiac arrhythmia, also known as an irregular heartbeat, occurs when an abnormality is observed in the heart’s normal rhythm. This can manifest as the heart beating too fast (tachycardia), too slow (bradycardia), or having pauses between heartbeats (skipped beats). These irregularities can be caused by various factors, including stress, nervousness, fear, or underlying medical conditions.
It’s important to note that arrhythmias can occur in any cat of any age or breed, but certain breeds, such as Persians, Maine Coon cats, and Himalayans, are more prone to experiencing irregular heartbeats (VRCC). Male cats and older cats are also more susceptible to abnormal heart rhythms.
Breeds Prone to Irregular Heartbeats
While cardiac arrhythmia can occur in any cat, certain breeds have a higher predisposition to developing this condition. Breeds such as Ragdolls, Himalayans, and Siamese are more susceptible to structural heart disease and arrhythmias (PetMD). The underlying causes of these breed predispositions are still being studied, but it’s important for owners of these breeds to be aware of the potential risks and to monitor their cats’ heart health closely.
By understanding what cardiac arrhythmia is and which breeds are more prone to irregular heartbeats, cat owners can be proactive in seeking veterinary care if any concerning symptoms arise. Early detection and appropriate treatment are crucial for managing this condition and ensuring the overall health and well-being of our feline companions.

Symptoms and Causes
When it comes to the health of our feline companions, it’s important to be aware of any potential signs of cat heart palpitations. Recognizing the symptoms and understanding the common causes of irregular heartbeats can help in early detection and prompt treatment.
Signs of Cardiac Arrhythmia
Symptoms of irregular heartbeats in cats can vary and may not always be observable. One common sign is changes in heart rate, which can manifest as a heartbeat that is too fast or too slow. Additionally, you may notice skipped beats or other abnormalities in the cycling of electrical impulses that regulate the heart’s beating. In some cases, the only noticeable difference may be an audible change when listening to the heart with a stethoscope. More severe arrhythmias may present additional symptoms, which can come and go rather than being constant (Wag Walking).
Common Causes of Irregular Heartbeats
Irregular heart rhythms in cats can have various causes, with each type of arrhythmia described based on how the rhythm differs from a normal heartbeat. Some of the common causes of irregular heartbeats in cats include:
-
Electrolyte Imbalance: An imbalance in electrolytes, such as potassium or calcium, can disrupt the normal electrical conduction in the heart, leading to irregular heartbeats.
-
Heart Diseases: Various heart conditions, such as hypertrophic cardiomyopathy or dilated cardiomyopathy, can result in abnormal heart rhythms.
-
Kidney Disease: Cats with kidney disease may experience imbalances in electrolytes and fluid levels, which can affect the heart’s electrical activity and lead to irregular heartbeats.
-
Hyperthyroidism: An overactive thyroid gland can increase the heart rate and cause irregularities in the heartbeat (VRCC).
While an irregular heart rhythm does not always indicate heart disease, it is essential to investigate the underlying cause, especially if the arrhythmia persists. If you notice any signs of cardiac arrhythmia in your cat, it’s important to consult with a veterinarian for a proper diagnosis and appropriate treatment.

Management and Care
When it comes to managing and caring for cats with cardiac arrhythmia, there are important considerations to ensure their well-being. This section focuses on outpatient vs. inpatient care and the significance of long-term monitoring and follow-up.
Outpatient vs. Inpatient Care
The type of care required for a cat with cardiac arrhythmia depends on the severity of the condition and the overall health of the cat. In some cases, outpatient care may be sufficient, allowing the cat to receive treatment while remaining in the comfort of its home. Outpatient care often involves the administration of medication to control the irregular heartbeats and regular follow-up examinations to monitor the cat’s progress.
However, in more severe cases or when there are complications, inpatient care may be necessary. This typically involves admission to a veterinary hospital where the cat can receive close monitoring and specialized treatments. Intravenous fluid therapy may be administered to address any electrolyte imbalances, and other interventions may be implemented as needed. The decision between outpatient and inpatient care will be made by the veterinarian based on the individual needs of the cat.
Long-Term Monitoring and Follow-Up
Regular monitoring and follow-up are crucial for cats with cardiac arrhythmia to ensure their condition is properly managed. This includes scheduled examinations, such as blood work, electrocardiograms (ECG), and echocardiography. These tests help assess the cat’s heart health, measure treatment success, and monitor disease progression.
For cats with atrial fibrillation, additional diagnostic procedures such as chest radiographs (X-rays) and heart ultrasounds may be recommended to evaluate the overall heart function and detect any potential complications. Regular follow-up appointments with the veterinarian are essential to track the cat’s response to treatment and make any necessary adjustments.
It’s important to note that not all cats with irregular heart rhythms require treatment if they are not showing signs of health compromise. In such cases, regular yearly health checks with the veterinarian may be sufficient. The veterinarian will provide guidance on the frequency of follow-up visits based on the cat’s specific condition and response to treatment.
By closely monitoring and following up with the veterinarian, cat owners can ensure that their feline friends receive the appropriate care and interventions necessary to manage their cardiac arrhythmia. Regular examinations, tests, and adjustments to the treatment plan, if needed, can help maintain the cat’s overall health and well-being.

Specific Types of Arrhythmias
When it comes to cat heart palpitations, different types of arrhythmias can occur. In this section, we will focus on two specific types: atrial fibrillation in cats and rapid heart contractions in atrial fibrillation.
Atrial Fibrillation in Cats
Atrial fibrillation in cats is characterized by very rapid contractions or twitching of the heart muscle, confined to the atria, which are the top chambers of the heart. It can occur as a secondary condition to heart disease or, in some cases, as a primary heart problem in large breed cats (VCA Canada).
The ventricles, which are the lower chambers of the heart, may contract more rapidly than normal, and the rhythm may be either regular or irregular. Cats with atrial fibrillation may exhibit signs related to underlying heart disease, such as exercise intolerance, exhaustion after minimal exertion, coughing, or difficulty breathing. The irregular heart rhythm can sometimes sound like an extra heart sound is present (VCA Canada).
Rapid Heart Contractions in Atrial Fibrillation
The rapid heart contractions in atrial fibrillation can be caused by various factors, including chronic heart valve disease, disease of the heart muscle itself (cardiomyopathy), or, rarely, heart disease present at birth. In some cases, no specific cause is determined, and it is referred to as idiopathic atrial fibrillation.
Treatment options for atrial fibrillation in cats focus on managing the condition and any underlying heart disease. Medications that slow the rate of conduction of electrical signals between the atria and the ventricles, such as beta-adrenergic blockers like atenolol or calcium-channel blockers like diltiazem, may be prescribed. Medical management also involves treating underlying heart disease, relieving excess fluid, controlling hypertension, and assisting the heart in beating more effectively.
Monitoring and follow-up for cats with atrial fibrillation are crucial. This may involve closely monitoring heart rate, follow-up electrocardiograms (ECGs) to measure treatment success, and recommending radiographs of the chest (X-rays) and heart ultrasounds to assess heart health and monitor disease progression.
If you suspect your cat may have an irregular heartbeat or any signs of cardiac arrhythmia, it is essential to consult with a veterinarian. They can provide a proper diagnosis and recommend the most suitable feline cardiac arrhythmia treatment options to help manage your cat’s condition.
Medication and Therapies
When it comes to managing cat heart palpitations or feline cardiac arrhythmia, there are several medication and therapeutic approaches available. These treatments aim to control and regulate irregular heartbeats, improving the overall well-being of the cat.
Medications for Managing Arrhythmia
Medication plays a crucial role in the treatment of cardiac arrhythmia in cats. The specific medication prescribed will depend on the type and severity of the arrhythmia, as well as any underlying health conditions. Common medications used to manage arrhythmia in cats include:
-
Beta-adrenergic blockers: These medications, such as atenolol, help slow down the heart rate and reduce the force of contractions. They work by blocking the effects of certain hormones that can contribute to irregular heartbeats.
-
Calcium-channel blockers: Medications like diltiazem are used to control the rate and rhythm of the heartbeat by blocking the entry of calcium into the heart muscle cells. This helps to stabilize the electrical signals in the heart.
-
Anti-arrhythmic drugs: In some cases, anti-arrhythmic drugs such as mexiletine or sotalol may be prescribed to restore and maintain a normal heart rhythm. These medications work by regulating the electrical activity in the heart.
It’s important to note that medication should only be prescribed and administered under the guidance of a veterinarian. Dosage and frequency will be determined based on the individual needs of the cat and may require periodic adjustment.
Therapeutic Approaches for Irregular Heartbeats
In addition to medication, there are therapeutic approaches that can be used to manage irregular heartbeats in cats. These approaches aim to improve heart function and minimize the impact of arrhythmia on the cat’s overall health. Some therapeutic options include:
-
Outpatient care: For cats with milder cases of arrhythmia, outpatient care may be sufficient. Regular check-ups with a veterinarian to monitor the cat’s heart health and adjust medication as needed can be an effective approach.
-
Hospitalization: In more severe cases, hospitalization may be required, especially if there are electrolyte imbalances or underlying health conditions that need to be addressed. Intravenous fluid therapy can help restore balance and stabilize the cat’s condition.
-
Pacemaker installation: In rare cases where medication and other therapies are not effective, a veterinary cardiologist may recommend the installation of a pacemaker. A pacemaker helps regulate the heart’s electrical signals, ensuring a steady heartbeat.
Regular monitoring and follow-up are essential in managing arrhythmia in cats. This may include periodic electrocardiograms (ECGs) to evaluate the success of treatment, radiographs of the chest (X-rays) to assess heart health, and heart ultrasounds to monitor disease progression (VCA Canada). The treatment plan should be tailored to the specific needs of the cat, considering factors such as the type and severity of the arrhythmia, overall health, and response to medication.
Remember, it is crucial to consult with a veterinarian who specializes in cardiology to determine the most appropriate medication and therapeutic approach for managing irregular heartbeats in cats. With proper treatment and care, cats with cardiac arrhythmia can lead happy and quality lives.
