Abstract 20382: Comparison of Outcomes After Rhythm or Rate Control Strategy for the New-Onset Atrial Fibrillation in Critically Ill Sepsis Patients Managed in the Medical Intensive Care Unit

Introduction: Data regarding effective rhythm or rate management for new onset atrial fibrillation (AF) in critically ill sepsis patients managed in the medical intensive care unit (MICU) are sparse. Hypothesis: We tried to compare the outcomes after rhythm or rate control strategy in these patients. Methods: A total of 5,383 sepsis patients were managed in MICU of Asan Medical Center from 2007 through 2015. Among these patients, 482 experienced new-onset AF, and the medical records of them (mean 68.2 years old, 68.9% male, median CHADS2VASC score 3, median APACHEII score 24) were reviewed. After exclusion of 34 patients who underwent urgent electrical cardioversion, patients were divided into two groups (rhythm control, 43.5%; rate control group, 56.7%) according to the initial management strategy. The main outcomes of the current study were rate of mortality, thromboembolism, and sinus conversion at 28 days after AF onset. Results: ICU interventions such as mechanical ventilator, inotropics or vasopress...
