Treatment of Friedreich Ataxia with Permanent, Persistent or Paroxysmal Atrial Fibrillation

Atrial fibrillation — whether permanent, persistent, or paroxysmal — and other atrial tachyarrhythmias represent an important comorbidity in individuals with Friedreich ataxia. Managing the cardiac rhythm in this population requires a specific evidence-based approach distinct from standard atrial fibrillation care.

The protocol prioritises maintaining a normal cardiac rhythm over rate control. For individuals who remain severely symptomatic despite initial management, a procedural intervention targeting the arrhythmia source is among the options addressed in the full regimen — but the complete decision algorithm, indications, and sequencing are detailed in the structured protocol.
