The order in which treatment recommendations appear in this table within each class of recommendation does not necessarily reflect a preferred sequence of administration. Please refer to text for details. For pertinent drug dosing information please refer to the ACC/AHA/ESC Guidelines on the Management of Patients With Atrial Fibrillation.

AT indicates atrial tachycardia; DC, direct current; MAT, multifocal atrial tachycardia.

  • Excluded are patients with MAT in whom beta blockers and sotalol are often contraindicated due to pulmonary disease.

  • All listed drugs for acute treatment are administered intravenously.

  • Flecainide, propafenone, and disopyramide should not be used unless they are combined with an AV-nodal-blocking agent.
