Types
The following types of supraventricular tachycardias are more precisely classified by their specific site of origin. While each belongs to the broad classification of SVT, clinicians prefer to use the specific term/diagnosis, when possible:
sinoatrial origin:
- Sinoatrial nodal reentrant tachycardia (SNRT)
atrial origin:
- Ectopic (unifocal) atrial tachycardia (EAT)
- Multifocal atrial tachycardia (MAT)
- Atrial fibrillation with a rapid ventricular response
- Atrial flutter with a rapid ventricular response
- (Without rapid ventricular response, fibrillation and flutter are usually not classified as SVT)
atrioventricular origin (junctional tachycardia):
- AV nodal reentrant tachycardia (AVNRT) or junctional reciprocating tachycardia (JRT)
- Permanent (or persistent) junctional reciprocating tachycardia (PJRT), a form of JRT which occurs predominantly in infants and children but can occasionally occur in adults
- AV reciprocating tachycardia (AVRT) - visible or concealed (including Wolff-Parkinson-White syndrome)
- Junctional ectopic tachycardia (JET)

Famous quotes containing the word types:
“Our major universities are now stuck with an army of pedestrian, toadying careerists, Fifties types who wave around Sixties banners to conceal their record of ruthless, beaverlike tunneling to the top.”
—Camille Paglia (b. 1947)
“If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.”
—Henry David Thoreau (1817–1862)
“The bourgeoisie loves so-called “positive” types and novels with happy endings since they lull one into thinking that it is fine to simultaneously acquire capital and maintain one’s innocence, to be a beast and still be happy.”
—Anton Pavlovich Chekhov (1860–1904)
