Figure 5 Success rates for the termination of atrial fibrillation (AF) with rapid burst pacing. Shown are the point estimates and the 95% confidence intervals for predicting the probability of a successful termination of AF. The results from each rapid pacing duration (1 to 4 s) are shown for pacing from the right atrium (RA), left atrium (LA), and biatrial pacing (BiA). A significant increase in the efficacy of the rapid atrial pacing for the termination of AF is seen with biatrial pacing synchronized to an organization index >0.5. With this configuration, a 3-s rapid pacing window had the highest success rate (24.7%).
