The treatment of choice for symptomatic AT is catheter ablation. In an experienced center up to 90% of the AT can be ablated. Vagal manoeuvres or adenosine can be effective in terminating focal AT. If AT persist DC cardioversion can be indicated. Recurrent episodes of AT can be prevented with anti-arrhythmic medication, for instance with beta-blockers or calcium antagonists. However not all AT are sensitive to medication and success rate of medication is usually low. | The treatment of choice for symptomatic AT is catheter ablation.
