Initial management of focal<unk>  should focus on addressing underlying causes: treating acute illness, cessation of stimulants, stress reduction, appropriately managing digoxin toxicity, or chronic disease management. The ventricular rate is controllable with the use of beta blockers or calcium channel blockers. If<unk>  tachyarrhythmia persists and the patient is symptomatic, the patient may benefit from class IA, IC, or class III antiarrhythmics. Catheter ablation of focal<unk>  may be appropriate in patients failing medical therapy.
