The Effect of Electrode Size and Interelectrode Spacing on Electrograms A voltage map with Thermocool (top left panel; 3.5 mm tip and 1 mm ring) and Pentaray (top right panel; each electrode 0.8 mm2) are shown. The red area is <0.5 mV. The bipolar signal recorded in the red area was 0.24 mV (top left panel) and was broad and fragmented. Recordings from the same site with a Pentaray show normal bipolar amplitude and width (bottom panel).
