Q; What are 2 types of Atrial flutter?

Answer:

Type I atrial flutters (tricuspid valve isthmus dependent): Catheter ablation is typically successful and recurrence is less than 5%. Postprocedure anticoagulation with warfarin is usually continued for 4-6 weeks.

Type II atrial flutters (non—tricuspid valve isthmus dependent): These circuits are amenable to catheter ablation but require advanced mapping systems. Recurrence is more common and may also require the use of antiarrhythmic agents for suppression.
