Increased Heart Rate Due to Premature Contractions in Cats



If your cat is stable, electrolyte abnormalities will be corrected using fluid administration. Echocardiogram and use a 24-Holter to establish a true baseline of the arrhythmia quantity and quality.


If the cat is unstable (inactive and lying down, weak, or frequent fainting), immediate intravenous treatment in a hospital setting with continuous ECG monitoring may be required. Once the arrhythmia is controlled and your cat's blood pressure has stabilized, oral medication should be started. The medication will be based on your cat's overall health, and how well your cat is able to tolerate the episodes of VT and how frequently they occur. Medications may be given to suppress future episodes. A follow-up 24-hour Holter will be required to test the efficacy of the anti-arrhythmic medication.


Living and Management


Unfortunately, cats with ventricular tachycardia can sometimes die suddenly. Your veterinarian will schedule subsequent follow-up appointments with you for your cat as necessary to try to avoid this possibility.
