Treatment of Regular Wide QRS Complex Tachycardia When Supraventricular Tachycardia Is Suspected

Clinical Scenario

Haemodynamically tolerated

This protocol addresses patients presenting with a regular wide QRS complex tachycardia in whom supraventricular tachycardia (SVT) is the suspected mechanism, and who show no signs of haemodynamic instability.

Treatment Goal

Termination of the tachycardia with conversion to sinus rhythm

First-Line Approach (Partial Overview)

When SVT is considered the likely underlying mechanism, a specific pharmacological or physiological intervention — carried out under continuous ECG monitoring — is the recommended first step. The complete regimen, including which intervention to use and how, is contained in the full structured protocol.

In patients presenting with a regular haemodynamically tolerated wide QRS complex tachycardia suspected for SVT, administration of adenosine or vagal manoeuvres should be considered.

Administration of adenosine or vagal manoeuvres with continuous recording of 12-lead ECG should be considered if supraventricular tachycardia (SVT) is likely.
