A, Freedom from atrial tachyarrhythmia. The cumulative event-free rate was estimated by using the Kaplan–Meier method. B, Freedom from sinus node dysfunction. The cumulative event-free rate was estimated by using the Kaplan–Meier method. APC, atriopulmonary connection; IB, intra-atrial baffling; EC, extracardiac conduit.

3. Figure 2
Chronologic changes in P-wave characteristics. Changes in maximum P-wave duration and P-wave dispersion were analyzed with the general linear mixed model, with years as a fixed effect and patients as a random effect. x, Years after surgical intervention. APC, Atriopulmonary connection; IB, intra-atrial baffling; EC, extracardiac conduit.
