Figure 2
Examples of abnormal EGMs recordings from animals with myocardial infarction. Shown are the EGM recordings in RV and LV in the sinus (a, c, e, g) and paced (b, d, f, h) condition. Tracings (a) and (b) show RVA signals, c and d represent normal healthy myocardium recordings. The following recordings are all acquired in non-healthy tissue. In (e) and (f) the local EGM recorded by the mapping catheter displays an isolated potential (oblique arrows) that is separated from the ventricular EGM by an isoelectric line of at least 20 ms. Finally, (g) and (h) are the recorded EGM fractionated and the width is > 102 ms; (RVA = Right ventricular apex, LV = left ventricle).
