Summary

Maintaining normal heart rhythm (sinus rhythm) in atrial fibrillation is challenging. Rate control may offer a safer alternative with a trend towards lower mortality, especially in high-risk patients.

Area of Science:

  • Cardiology
  • Pharmacology

Context:

  • Atrial fibrillation management traditionally focused on rhythm control using antiarrhythmic drugs.
  • Drug selection for rhythm control is complex, with potential for poor therapeutic indices and contraindications in specific patient groups (e.g., heart failure, coronary artery disease).

Purpose:

  • To review treatment strategies for atrial fibrillation, comparing rhythm control with rate control.
  • To discuss the safety and efficacy of different antiarrhythmic drugs and rate-controlling agents.

Summary:

  • Rhythm control for atrial fibrillation (AF) involves cardioversion and antiarrhythmic drug therapy, but drug choice is difficult and safety concerns exist, particularly with Class I agents.
  • Rate control, achieved with calcium channel blockers, beta-blockers, or digitalis, is a viable alternative, especially when rhythm control is contraindicated or poorly tolerated.

  • Anticoagulation is crucial regardless of the chosen strategy (rhythm or rate control) due to the persistent risk of stroke in AF patients.

    • Impact:

    • Recent trials comparing rhythm and rate control strategies show no definitive superiority of one over the other.
    • However, available data suggest a potential trend towards lower mortality in patients managed with a rate control strategy for atrial fibrillation.
