The EHRA Practical Compendium of Antiarrhythmic Drugs (AADs) offers advice on these drugs, focusing on their clinical use and the global impact of cardiac arrhythmias. This document aims to provide practical instructions to clinicians in arrhythmia management through pharmacological strategies. The compendium highlights persistent challenges in arrhythmia treatment, including clinical constraints, procedural risks, and the complexity of certain arrhythmias. Notably, atrial fibrillation is highly prevalent, and the demand for invasive treatment often surpasses the capacity of existing healthcare systems. As a result, pharmacological management remains essential. This is particularly relevant for patients with cardiac implantable electronic devices or channelopathies, where ablation is often not a suitable option. AADs play a pivotal role in these scenarios. The compendium introduces the ABC framework for AAD therapy: A (Appropriate therapy), for patients in whom AADs are the best therapeutic option, B (Backup therapy), as adjunctive treatment to invasive procedures, such as catheter ablation, and C (Complementary therapy), in combination with other therapies. The document provides detailed insights into the mechanisms of action, efficacy, safety profiles, and drug interactions of each class of AADs. Additionally, the compendium covers practical considerations, including initiation, combination strategies, monitoring, follow-up, special populations, and adverse effect management, with an emphasis on proarrhythmia risk mitigation. It also explores the integration of AADs with other therapeutic modalities, promoting a synergistic approach to optimize patient outcomes. In summary, this compendium serves as an indispensable resource for clinicians, offering practical advice and evidence-based insights to navigate the complexities of arrhythmia management effectively.
