A Fib 4: Rhythm Control Medications

Tina discusses the following rhythm control medications for atrial fibrillation:

Class 3 antiarrhythmics: blocks potassium channels and prolongs action potential duration

  • Amiodarone
  • Dronedarone
  • Sotalol

Class 1 antiarrhythmics: blocks sodium channels, which results in a slowed atrial conduction, lengthens atrial refractoriness, and suppresses automaticity

  • propafenone
  • flecainide
