Circulation: Arrhythmia and Electrophysiology publishes high-quality, clinically relevant articles focusing on advances in the understanding of the pathophysiology,
diagnosis, and treatment of cardiac arrhythmias. The journal reflects the rapid evolution of cardiac electrophysiology as a discipline in its own right, and presents critical
new research on topics related to clinical applications such as devices for arrhythmia management, catheter ablation, the pathophysiology of the arrhythmia substrate, and
novel biologic therapies.
