In some cats, atrial standstill is not a life-threatening condition and no hospitalization is required. However, in others it may be serious enough to require immediate intensive care. Such animals typically have an abnormally high blood potassium level or are suffering from severe dehydration. In these cases, intravenous fluid therapy is used to stabilize the animal. If the cat's heart rhythm cannot be rectified by ordinary means, a pacemaker may be surgically implanted into the chest or abdomen. This small medical device helps control the abnormal heart atria activity.
Living and Management
The prognosis of the cat depends on the underlying disease causing the heart rhythym disturbance. If it is corrected quickly and (when present) hyperkalemia is reversed, the long-term prognosis is excellent.
Your cat will require rest in a stress-free environment, away from other pets and active children, to help control the symptoms of persistent atrial standstill. Even with a pacemaker, however, the symptoms of lethargy and weakness may persist. Cats with pacemakers also require regular follow-up exams and periodic ECGs to monitor the effectiveness of the device and the heart's rhythm.
