2.3 Anti-arrhythmic drugs

General guidance

For NHS Dudley Atrial Fibrilation (AF) Primary Care Diagnosis and Management Pathway click here

  • Management of arrhythmia requires precise diagnosis of the type of arrhythmia, and electrocardiography is essential.
  • Spontaneous ectopic beats rarely require treatment other than reassurance. If they are particularly troublesome beta-blockers may be useful.
  • In atrial fibrillation ventricular rate can usually be controlled with digoxin. If this is insufficient at rest or during exercise a beta-blocker or verapamil may be added. Anticoagulation is indicated especially in valvular heart disease. Aspirin is less effective then warfarin but may be appropriate if there are no other risk factors for stroke.
  • The concomitant use of verapamil and digoxin should be avoided due to the risk of a serious drug-drug interaction.
  • For other arrhythmia seek specialist advice.
