Treatment of Antidromic Atrioventricular Reentrant Tachycardia in the Haemodynamically Stable Patient

This page covers the evidence-based management approach for a haemodynamically stable patient presenting with antidromic atrioventricular re-entrant tachycardia (antidromic AVRT).

Clinical Scenario

The patient is haemodynamically stable and presenting with antidromic atrioventricular re-entrant tachycardia. Haemodynamic stability is the defining feature of this protocol's clinical setting, distinguishing it from unstable presentations that require immediate electrical intervention.

Management Approach

The protocol for this scenario centres on specific intravenous antiarrhythmic agents, with synchronized DC cardioversion as a further option within the management pathway.

The complete regimen — including the full list of agents, the decision sequence, and the criteria for each step — is available in the full structured protocol below.

In antidromic AVRT, i.v. ibutilide or procainamide or i.v. flecainide or profanenone or synchronized DC cardioversion should be considered if vagal manoeuvres and adenosine fail.
