Figure 3.
A schematic diagram illustrating distribution of four resumption sites across the surgical incision. The red line shows the incision. The blue arrows indicate activation of the re-entrant circuit of incisional AT (A, B ) and activation sequence of the lateral right atrium during pacing from the low lateral right atrium (C, D ). Numbers in circle indicate the sequence and location of ablation of the reconduction sites on the incision. Sites of ablation are indicated by pink dots. Note that two penetration points (circled number 3 and 4 indicated by short solid orange line) might demonstrate functional conduction block during incisional AT.
AT, atrial tachycardia.
