Supraventricular tachycardia (SVT) is common; it is a broad term covering many types of supraventricular arrhythmias in the atria or atrioventricular node.
In case of acute SVT, vagal manoeuvres and pharmacological therapy can be effective in arrhythmia termination. Catheter-based radiofrequency ablation has revolutionised therapy for many SVTs, and newer techniques have significantly improved ablation efficacy and reduced periprocedural complications and procedure times. Cryoablation is currently being investigated as an alternative, although the long-term effectiveness of this procedure currently limits its use for many SVTs.
