Key result
Conventional antiarrhythmic drugs remain justified for patients preferring medical therapy, those unsuitable for catheter ablation, or as adjunctive treatment for recurrent arrhythmias.
Why the study?
What is the role of conventional antiarrhythmic drugs in the era of catheter ablation and implantable devices?
What is the role of conventional antiarrhythmic drugs in the era of catheter ablation and implantable devices?
Conventional antiarrhythmic drugs still have a role in modern arrhythmia management, particularly for patients who prefer them, are unsuitable for ablation, or require adjunctive therapy, though drug interactions and side effects remain significant challenges.
Answers are grounded in this paper and cite their sources.
Supports continued justification for antiarrhythmics in select patients; leaves open comparative trials integrating ablation and devices.
BACKGROUND: Long-term use of antiarrhythmic drugs is less important today as curative catheter ablation often is more appropriate, and the use of implantable cardioverter-defibrillators is an option. Many patients, however, still prefer, or are merely offered drug treatment. OBJECTIVES: To review current literature on conventional antiarrhythmic drugs in the intervention and device era, with focus on efficacy, side effects, drug interactions and pro arrhythmic problems in adult patients. RESULTS/CONCLUSION: Antiarrhythmic drugs are still justified in patients who prefer this treatment or who cannot be cured by catheter ablation owing to technical problems or lack of treatment capacity. Another main use of these drugs is adjunctive treatment after unsuccessful catheter ablation or when arrhythmias frequently recur in a patient with an implanted device. Drug interactions owing to treatment for comorbidity represent a serious challenge.

Knut Gjesdal (2009) conducted a review in Arrhythmias. Conventional antiarrhythmic drugs was evaluated on Efficacy, side effects, drug interactions and pro arrhythmic problems. Conventional antiarrhythmic drugs remain justified for patients preferring medical therapy, those unsuitable for catheter ablation, or as adjunctive treatment for recurrent arrhythmias.
