Minimizing Esophageal Heating During Radiofrequency Catheter Ablation.

In the distant electrode configuration, the ablation volumes produced by HPSD were comparatively smaller and did not reach statistical significance (Tables 1 and 2 ). 3.2 Local Dispersive Electrode Placement Increased Esophageal Heating, and Lesions Sizes Compared to a Distant Configuration Ablation lesion dimensions and esophageal heating were influenced by the location of the local dispersive electrode (Figure 3 ).
