Comparison of Electrogram Characteristics Within the Infarct Zone at 3 Different Locations In location 1 at the septal border of the infarct, the standard M1-M2 electrogram shows a low-amplitude electrogram, whereas the microelectrodes (Mic1-Mic2, Mic2-Mic3, and Mic3-Mic1) show a narrow high-amplitude electrogram, improving delineation of the infarct border zone. In location 2, the microelectrodes record a distinct near-field late potential that is not shown with standard electrodes recorded simultaneously and gained similarly. Location 3, recorded at the lateral border of the infarct, shows low-amplitude electrogram that is similar for the standard electrodes and microelectrodes. Eran Leshem et al.
