Figure 7 LA Activation Prolongs for a Wider Range of Beats in Persistent Than Paroxysmal AF

(A) Paroxysmal AF, AT prolongs only at very early DI (<20 ms; i.e., preserved conduction restitution), seen in actual and normalized plots. (B) Persistent AF, AT prolongs at longer DI (<108 ms; i.e., broad conduction restitution) in both plots. See Table 3. Abbreviations as in Figures 1 to 3.
