Cardiac Arrhythmias in Cats: Welfare and Management

Feline cardiac arrhythmias range from incidental findings to life-threatening emergencies. This guide covers welfare impacts and management approaches.

Key Facts

Arrhythmias are abnormal heart rhythms that can affect cardiac output
Common feline arrhythmias include atrial fibrillation, ventricular arrhythmias, and bradyarrhythmias
Underlying cardiomyopathy is the most common cause in cats
Some arrhythmias cause no clinical signs; others cause collapse or sudden death
Treatment depends on the type and haemodynamic significance of the arrhythmia
Regular monitoring is essential for cats on anti-arrhythmic therapy

Welfare Considerations and Management

Welfare-centred management of feline arrhythmias requires specialist cardiology assessment to determine clinical significance and guide treatment. Arrhythmias causing haemodynamic compromise (collapse, syncope) require prompt treatment. Rate control with diltiazem may be appropriate for atrial fibrillation. Anti-arrhythmic medications require careful dosing and monitoring. Concurrent management of underlying heart disease is essential.

What You Can Do

Seek specialist cardiology assessment for any cat with suspected arrhythmia
Monitor cats at home for episodes of collapse, weakness, or rapid breathing
Administer anti-arrhythmic medications precisely as directed by your cardiologist
Avoid stress and overexertion in cats with significant cardiac arrhythmias
