Vagal maneuvers or adenosine can be effective in terminating focal AT. If AT persist and is drug-resistant 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. If these drugs are unsuccessful Class Ic in combination with AV-nodal-blocking agents or Class III drugs can be tried. The treatment of choice for symptomatic AT is catheter ablation. In an experienced center up to 90% of the AT can be ablated. Multifocal atrial tachyardia is difficult therapy is usually directed at the management of underlying disease. | Vagal maneuvers or adenosine can be effective in terminating focal AT.
