In general,<unk>  should be managed in the same way as atrial fibrillation. Because both rhythms can lead to the formation of a blood clot in the atrium, individuals with<unk>  usually require some form of anticoagulation or antiplatelet agent. Both rhythms can be associated with dangerously fast heart rates and thus require medication to control the heart rate (such as beta blockers or calcium channel blockers) and/or rhythm control with class III antiarrhythmics (such as ibutilide or dofetilide). However,<unk>  is more resistant to correction with such medications than atrial fibrillation. For example, although the class III antiarrhythmic agent ibutilide is an effective treatment for<unk> , rates of recurrence<unk> ter treatment are quite high (70–90%). Additionally, there are some specific considerations particular to treatment of<unk> . Cardioversion<unk>  is considerably more sensitive to electrical direct current cardioversion than atrial fibrillation, with a shock of only 20 to 50 Joules commonly being enough to cause a return to a normal heart rhythm (sinus rhythm). Exact placement of the pads does not appear important. Ablation Due to the reentrant nature of<unk> , it is often possible to ablate the circuit that causes<unk>  with radiofrequency catheter ablation. Catheter ablation is considered to be a first-line treatment method for many people with typical<unk>  due to its high rate of success (>90%) and low incidence of complications. This is done in the cardiac electrophysiology lab by causing a ridge of scar tissue in the cavotricuspid isthmus that crosses the path of the circuit that causes<unk> . Eliminating conduction through the isthmus prevents reentry, and if successful, prevents the recurrence of the<unk> . Atrial fibrillation often occurs (30% within 5 years)<unk> ter catheter ablation for<unk> .
