Abstract

There is limited data on clinical outcomes of delayed cardioversion (DCV) compared with early cardioversion (ECV) in paroxysmal atrial fibrillation (AF) patients. We utilized data from National Inpatient Sample (2015-2020) and propensity-score matched analysis to determine adjusted odds ratio (aOR) of major clinical outcomes, including 17,879 AF cases: 9725 and 8154 underwent ECV and DCV, respectively. Compared with ECV, DCV was associated with higher odds of acute heart failure (AHF; aOR 1.79 [1.67-1.92]; p < 0.01), median length of stay (4 vs 2 days; p < 0.01) and cost of hospitalization ($33,410 vs $21,738; p < 0.01) with no significant difference in inpatient mortality and other cardiovascular and neurological outcomes. Compared with ECV, DCV was associated with more AHF and resource utilization.
