Arrhythmias are prevalent, complex, and potentially life-threatening complications encountered in acute and intensive care settings. Critically ill patients present unique challenges for arrhythmia management due to complex underlying conditions, acute physiologic disturbances, and frequent need for rapid intervention. Improving our understanding of the mechanisms, diagnostic strategies, and management pathways for arrhythmias in these patients is vital to improving outcomes.

This Research Topic aims to advance the knowledge base and clinical practice surrounding the management of all types of arrhythmias within acute care and intensive care units. We seek contributions that address clinical, translational, and basic science aspects, including but not limited to:

• Epidemiology and risk factors: Incidence of arrhythmias and predisposing factors in acute and intensive care populations

• Pathophysiology: Mechanistic insights into arrhythmia development in critically ill and postoperative patients

• Diagnostics: Innovations in monitoring, early detection, and risk stratification in the ICU

• Acute management: Optimal protocols for pharmacological and non-pharmacological intervention, application of imaging methods in management, including advanced cardiac life support (ACLS), pacing, and ablation

• Challenges and outcomes: Hemodynamic management, prevention of recurrences, and long-term outcomes

• Multidisciplinary approaches: Role of collaborative care among cardiologists, intensivists, and acute care teams

• Future directions: Emerging technologies, digital health, and personalized medicine in arrhythmia care

We welcome original research, clinical trials, systematic or narrative reviews, mini-reviews, case reports, and expert opinions. By gathering multidisciplinary insights, this Topic will serve as a resource for clinicians, researchers, and allied health professionals aiming to improve patient care and advance the field of arrhythmia management in acute and intensive care environments.
