Special issues published by the Journal of Arrhythmia bring together themed collections of original research, review articles, and clinical guidance on topics of pressing relevance to the arrhythmia community. Each collection is curated by guest editors and aims to consolidate current knowledge while highlighting emerging questions and controversies. Readers ranging from practicing electrophysiologists to trainees and allied health professionals can use these issues to gain a structured overview of a given subject, moving from foundational mechanisms to practical management strategies in a single, cohesive volume.

One recurring theme across many special issues is inherited arrhythmia syndromes, including Brugada syndrome and other channelopathies that carry significant risk of sudden cardiac death. These collections examine genetic testing, risk stratification, electrocardiographic patterns, and the role of implantable cardioverter-defibrillators in affected patients. By drawing together contributions from international experts, the journal helps translate bench-side discoveries into bedside decision-making, offering clinicians a comprehensive reference for evaluating and managing patients who present with these often challenging and heterogeneous conditions.

Device therapy represents another major focus, with special issues addressing the full spectrum of implantable cardiac electronic devices, from single- and dual-chamber pacemakers to more advanced cardiac resynchronization and defibrillator systems. Authors explore implantation techniques, programming strategies, remote monitoring, and the management of device-related complications, including infection surveillance and lead extraction. These collections are designed to support both the seasoned implanter and the clinician who cares for device patients in everyday practice, balancing technical detail with broader considerations of patient selection and long-term follow-up.

Atrial fibrillation and its contemporary management also feature prominently among the special issues, reflecting the growing burden of this arrhythmia worldwide. Contributions cover pharmacological rate and rhythm control, catheter ablation approaches, stroke prevention with anticoagulation, and lifestyle modifications that influence disease progression. In addition, themed collections have addressed topics such as pediatric arrhythmias, clinical pharmacology, and the latest advances in ablation technology. Together these issues serve as valuable educational resources, keeping readers current with the evolving evidence base and helping to shape best practices in arrhythmia care across diverse clinical settings.
