Increased Heart Rate Due to Premature Contractions in Dogs



If your dog 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 your dog 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 dog's blood pressure has stabilized, oral medication should be started. The medication will be based on your dog's overall health, and how well your dog is able to tolerate the episodes of VT and how frequently they occur. Medications may be given to suppress future episodes, and your dog's activity level will probably need to be minimized. A follow-up 24-hour Holter will be required to test the efficacy of the anti-arrhythmic medication.


Living and Management

Unfortunately, dogs with ventricular tachycardia will sometimes die suddenly. Exciting situations (i.e., those that cause the heart to speed up) will need to be avoided in order to avoid provoking a ventricular tachycardia episode. This appears to be especially true in regards to the Boxer breed. Your veterinarian will schedule subsequent follow-up appointments with you for your dog as necessary.
