Overview
Junctional tachycardia is a form of supraventricular tachycardia characterized by electrical impulse generation from the AV node.[1] It is a tachycardia associated with the generation of impulses in a focus in the region of the atrioventricular node.
Causes
Differentiation of Junctional Tachycardia from other Tachycardias
- Sinus tachycardia:
- Atrioventricular nodal reentrant tachycardia: It can appear similar to atrioventricular nodal reentrant tachycardia.[3]
One form is junctional ectopic tachycardia.
