The results of the Atrial Fibrillation Follow-Up Investigation of Rhythm Management (AFFIRM) and the Rate Control Versus Electrical Cardioversion for Persistent Atrial Fibrillation (RACE) study were presented in March 2002. These large studies showed no benefit of a rhythm-control strategy over a rate-control strategy in managing atrial fibrillation (AF). Cardioversion and atrioventricular junctional ablation are forms of rhythm control and rate control, respectively. The numbers of cardioversions and atrioventricular junctional ablations performed at the University of Virginia and the Medical College of Virginia during the 52 months before AFFIRM and RACE results were released and the 21 months afterward were compared. From January 1998 to March 2002, monthly averages of 31 ± 8 elective cardioversions and 6 ± 3 atrioventricular junctional ablations were performed; from April 2002 to December 2003, the monthly averages were 21 ± 6 cardioversions (p = 0.001) and 9 ± 3 ablations (p = 0.001). AF management changed at these institutions shortly after the RACE and AFFIRM results were released.
