(Created page with "'''Atrioventricular reciprocating/reentry tachycardia''' (AVRT) is a paroxysmal tachycardia characterised by the formation of a re-entry circuit consisting of the AV node and the accessory pathway, usually precipitated by a premature atrial beat. AVRT may be orthodromic, which is the case in 95% of cases, or antidromic, in the remaining cases. AVRT is most commonly seen in Wolff-Parkinson-White syndrome. == Orthodromic AVRT == In...") |

Because antidromic AVRTs can be impossible to distinguish from VT, it should be treated similarly as other [[Wide-complex tachycardi|wide-complex tachycardia]]<nowiki/>s. Haemodynamically unstable paroxysmal tachycardias should be treated with synchronised electrical [[cardioversion]]. Stable patients should receive antiarrhythmics. AV-nodal blocking agents like [[adenosine]] are contraindicated as they may precipitate [[pre-excited atrial fibrillation]]. | Because antidromic AVRTs can be impossible to distinguish from VT, it should be treated similarly as other [[Wide-complex tachycardi|wide-complex tachycardia]]<nowiki/>s.
