Figure 3A: Ladder diagram illustrating supernormal nodal conduction. Black lines on the ladder diagram show nodal (AVN) conduction. Blue lines show accessory pathway (AP) conduction. Yellow bars represent the supernormal excitability period of the AVN. The red dotted line shows the point of supernormal AVN conduction. Figure 3B: Ladder diagram illustrating supernormal accessory pathway conduction. Black lines show nodal (AVN) conduction. Blue lines show accessory pathway (AP) conduction. Green bars represent the supernormal excitability period of the AP. The red dotted line shows the point of supernormal AP conduction.
