Dog: common
 
  
Cat: uncommon
 
 
Horse: common; male>female; Standardbreds and Draft horses are most affected
 
 
Cattle: common; especially dairy cattle
 
 
 
'''Atrial Fibrillation:''' Occurs when many ectopic waves of depolarisation spread throughout the atria.  While the atria fail to contract some of the disorganized depolarization waves are conducted through the AV node reaching the ventricles.  As a result the ventricles have a rapid, irregular rate.
 
 
 
'''Atrial Flutter:''' A rare unstable arrhythmia consisting of rapid atrial rate and abnormal atrial depolarization.  Atrial flutter is an arrhythmia that cycles between atrial fibrillation and sinus rhythm. 
 
 
 
====Causes====
 
Atrial pathology, pathology of other systems, electrolyte imbalances, drug interactions
 
 
 
'''ECG Appearance:''' lack of P waves (atrial fibrillation); small f waves (atrial flutter)
 
 
 
====Treatment====
 
Treat all underlying conditions
 
 
 
Dog & Cat: digoxin +/- diltiazem or +/- propranolol; quinidine or diltiazem (used in animals without cardiac failure or enlargement)
 
 
 
Horse: quinidine sulfate or treat congestive heart failure (furosemide, digoxin etc.)
 
 
 
Cattle: quinidine sulfate; Digoxin (given first if tachycardic)
