Treatment of Atrioventricular Nodal Reentry Tachycardia in Haemodynamically Stable Patients
When a patient presents with atrioventricular nodal re-entrant tachycardia (AVNRT) and remains haemodynamically stable — with no signs of circulatory compromise — a specific first-line approach is indicated before considering further steps.
Clinical scenario
Haemodynamically stable atrioventricular nodal re-entrant tachycardia, with no haemodynamic instability present.
Initial approach
Management begins with a defined set of vagal manoeuvres. The precise recommended technique and positioning are specified in the full structured protocol.
Additional steps beyond the initial manoeuvre are detailed in the complete regimen.
Treatment goal: Termination of the atrioventricular nodal re-entrant tachycardia.

- Vagal manoeuvres, preferably in the supine position with leg elevation, are recommended.
- Most data on the effectiveness of vagal manoeuvres and adenosine for acute termination of tachycardia are derived from mixed populations of SVT, as described in section 10.1.1 on the acute therapy of SVT in general, but it seems that they are less successful in AVNRT than in AVRT.
