Atrial Premature Complexes in Cats
 
Under normal circumstances, the heart works with exceptional synchronization between the various atrial and ventricular structures, resulting in a consistent rhythmic pattern. Atrial premature complexes result in an abnormal rhythmic disturbance, where the heart beats prematurely, before the normal timing, or pacing. 
 
Excluding animals born with a congenital heart disease, atrial premature complexes often affect older cats. Atrial premature complexes (APCs) can be seen on an electrocardiogram (EKG) as a premature wave called a P wave. ...read more
