Sotalol in atrial fibrillation

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Sotalol has been shown to be effective in the control of chronic atrial fibrillation.

It is thought that sotalol has two modes of action:

  • a class II beta-blocker action
  • a class III action which prolongs the action potential

The class II effects of sotalol mean that it is a useful choice in a patient with atrial fibrillation in combination with hypertension or ischaemic heart disease.
