Atrial fibrillation (AF) management depends on whether it is paroxysmal or sustained. Treatment focuses on suppressing episodes or controlling ventricular rate when cardioversion is not feasible.
Area of Science:
- Cardiology
- Electrophysiology
- Internal Medicine
Background:
- Atrial fibrillation (AF) is the most frequent sustained cardiac arrhythmia.
- AF incidence rises with age and is linked to heart disease, thyrotoxicosis, and alcohol.
- AF can manifest as self-terminating paroxysms or sustained arrhythmias.
Purpose of the Study:
- To outline management strategies for paroxysmal and sustained atrial fibrillation.
- To detail therapeutic options for rate control when cardioversion is unsuccessful.
- To present advanced interventions for refractory cases.
Main Methods:
- Review of pharmacological agents for arrhythmia suppression (Class 1C, 2, 3).
- Assessment of cardioversion feasibility and post-procedure management.
- Evaluation of rate-controlling medications (digoxin, beta-blockers, amiodarone, calcium channel blockers).
Main Results:
- Paroxysmal AF management targets episode suppression.
- Sustained AF requires a decision on cardioversion; if unsuccessful, rate control is prioritized.
- Advanced therapies like AV nodal ablation are considered for refractory cases.
Conclusions:
- Therapeutic approaches for atrial fibrillation are stratified based on arrhythmia type and patient factors.
- Rate control is a key strategy for sustained AF, especially when cardioversion fails.
- Atrioventricular nodal modification or ablation offers an alternative for intractable ventricular rate control.
