Overview
Rate control: focuses on slowing the ventricular rate to reduce symptoms and improve tolerance of AFib during rest and activity. Typical options include beta‑blockers, diltiazem/verapamil or digoxin depending on blood pressure, heart failure status and exercise needs.
Rhythm control: aims to restore and maintain sinus rhythm using antiarrhythmic drugs or cardioversion. Choice of therapy weighs contraindications and proarrhythmia risk; shared decision‑making is essential.
Catheter ablation: a procedural approach—often pulmonary vein isolation—to eliminate triggers/substrate. Best outcomes in paroxysmal AF; repeat procedures may be necessary.
Anticoagulation: personalized stroke prevention guided by CHA2DS2‑VASc and bleeding risk tools. DOACs are commonly preferred when appropriate; reassess after rhythm interventions.
Goals of Treatment
AFib care aims to relieve symptoms, improve quality of life, prevent stroke and heart failure, and reduce hospitalizations. Treatment is personalized based on AFib pattern, duration, comorbidities and patient preference, and often combines multiple approaches.
Rate Control
Medications
Beta‑blockers, non‑dihydropyridine calcium‑channel blockers (diltiazem/verapamil) and digoxin can slow AV‑node conduction to keep the ventricular rate in a tolerable range at rest and during activity. Choice depends on blood pressure, heart failure status and exercise requirements.
Targets and Monitoring
Symptoms and functional status guide targets; some patients do well with lenient control, others need stricter targets. Ambulatory monitoring and exercise assessment can help tailor therapy.
Rhythm Control
Antiarrhythmic Drugs
Class IC agents (e.g., flecainide, propafenone) and class III agents (e.g., sotalol, dofetilide, amiodarone) are used to maintain sinus rhythm or enable “pill‑in‑the‑pocket” cardioversion in selected patients. Contraindications, proarrhythmia risk and organ toxicities require careful selection and follow‑up.
Cardioversion
Electrical or pharmacologic cardioversion can restore sinus rhythm. Anticoagulation strategy depends on AF duration, TEE findings and stroke risk.
Catheter Ablation
Indications
PV isolation is effective for symptomatic paroxysmal AF when drug therapy fails or is undesired; persistent AF may require additional substrate ablation. Early referral is increasingly considered, especially in patients seeking rhythm control.
Outcomes and Risks
Success rates are higher in paroxysmal AF and with risk‑factor optimization. Complications are uncommon but include vascular injury, tamponade, PV stenosis and rare esophageal injury. Repeat procedures are sometimes needed.
Anticoagulation
Stroke and Bleeding Risk
Use scores such as CHA2DS2‑VASc for stroke and HAS‑BLED for bleeding risk estimation. Direct oral anticoagulants (DOACs) are often preferred over warfarin when not contraindicated. Shared decision‑making is central; reassess after rhythm interventions.
Risk‑Factor Modification
- Weight management and metabolic health
- Sleep apnea screening and treatment
- Alcohol moderation and caffeine awareness
- Blood pressure optimization and exercise
- Inflammation and comorbidity management
