Heart Disease of the Sinus Node in Cats




Only cats showing clinical signs need treatment, and only cats requiring electrophysiologic testing of the heart, or implantation of an artificial pacemaker will need to be hospitalized. Attempts to manage an abnormally fast or abnormally slow heart rate, without prior pacemaker implantation, carries a significant risk of worsening the extremes of the abnormal heart rate syndrome.


Living and Management


You will need to keep your cat's physical activity to a minimum while it is healing from this condition. Encourage rest in a quiet, non-stressful environment as much as possible, away from other pets or active children. Cage rest may be recommended for the interim. Although therapy for SSS may appear to work at the beginning of treatment, medical therapy commonly does not have long term benefits. The only solution in these instances is surgical correction.
