Atrioventricular reentrant tachycardia occurs when a reentrant circuit is present outside of the AV node through an abnormal conduction pathway that connects the atrium to the ventricles.

Atrioventricular nodal reentrant tachycardia (AVNRT ... such as atrial tachycardia (AT) and orthodromic reciprocating tachycardia (ORT). A study introduced a technique called the "last entrainment ...

Atrioventricular nodal reentrant tachycardia is the most common form of paroxysmal supraventricular tachycardia, or PSVT, in adults. AVNRT occurs when a reentrant circuit is present within the AV ...

Atrioventricular nodal re-entrant tachycardia (AVNRT) can trigger atrial fibrillation (AF), but the incidence of AVNRT as a cause of AF is unclear. Identification of patients with AVNRT could ...

In the case of reentrant circuits ... usually called orthodromic and antidromic, according to whether they proceed in the same or the opposite direction as during tachycardia.

Resetting with fusion. Left panel: a left ventricular extrastimulus (St) is delivered during a regular orthodromic tachycardia mediated by a left-sided accessory pathway. Right panel: left ...
