Small Animal: Common
Large Animal: Uncommon
a. '''Paroxysmal Atrial Tachycardia (PAT)='''regular rapid atrial contractions arising from atrial tissue outside the SA node
b. '''Atrioventricular Junctional Tachycardia (AJT)='''regular rapid atrial contractions arising from AV nodal tissue
c. '''Supraventricular Tachycardia''' a term used to include both PAT and AJT. Rapid premature beats occuring somewhere above the ventricles.
====Causes====
Result from pathological conditions in the cardiac atria, hypoxia, stress, digitalis toxicity, systemic hypertension etc.
'''ECG Appearance:''' Rapid heart rate, abnormal P wave (inverted) which can be preceded, be superimposed, or follow QRS complexes
====Treatment====
'''Small Animals'''
*Treat underlying cause
*Vagal manoeuvres (e.g. carotid sinus or ocular massage)
*Drug Treatment:
-If + for congestive heart failure treat with digoxin and other heart failure drugs
-If - for congestive heart failure treat with diltiazem, propranolol, or adenosine
*Avoid digoxin if a reentry mechanism is suspect in causing the supraventricular tachycardia
*Pacing methods
'''Large Animals'''
*Treat underlying cause
*Box rest with heart rate and rhythm monitoring
*If + for heart failure, give digoxin
*Vagal manoeuvres (e.g. carotid sinus or ocular massage)
*Quinidine sulfate[[Category:Altered Supraventricular Impulse Conduction]][[Category:To_Do_-_Cardiovascular]]
